A car travels from point A to B in 3 hours and returns back to point A in 5 hours. Points A and B are 150 miles apart along a straight highway. Calculate: a) Total distance and total displacement (in mile and meter) b) Average speed and Average velocity (in mile/hr and m/s​

Answers

The total distance covered by the car is 300 miles.

The total displacement covered by the car is zero.

The average speed of the car is 17.88 m/s.

The average velocity of the car is also zero.

Distance between the points A and B, d = 150 miles

Time taken by the car to travel from A to B, t₁ = 3 hours

Time taken by the car to travel from B to A, t₂ = 5 hours

a) Given that the car travelled from A to B and then back to A.

Therefore, the total distance covered by the car is,

Distance = 2 x d

Distance = 2 x 150

Distance = 300 miles

Since the car is travelling from A to B and then returning back to the initial point A, the total displacement covered by the car is zero.

b) The speed with which the car travelled from A to B is,

v₁ = d/t₁

v₁ = 150/3

v₁ = 50 miles/hr

v₁ = 22.35 m/s

The speed with which the car travelled from B to A is,

v₂ = d/t₂

v₂ = 150/5

v₂ = 30 miles/hr

v₂ = 13.41 m/s

Therefore, the average speed of the car is,

v = (v₁ + v₂)/2

v = (22.35 + 13.41)/2

v = 17.88 m/s

The left field fence in Boston's Fenway park is known as the green monster. The wall is 11.34m high, and is located 94.5m from home plate. The average exit velocity of a ball being struck by a major-league batter is 41.0m/s.


If a batter launches the ball in a direction 30° above the horizontal, will he hit a home run? (Hint: use horizontal motion to solve for t first)

Imagine that a batter hit a ball so that it was at the peak of its trajectory when it brushed against the top of the green monster.
Find the initial y velocity (Hint: need equation that does not involve time). Find the travel time.
Use that to to find the horizontal velocity.
Use the pythagorean theorem to find the total initial velocity.

Answers

To determine whether the batter will hit a home run, we need to analyze the ball's trajectory and determine if it will clear the 11.34m high Green Monster wall.

Let's break down the problem into steps:

Step 1: Calculate the time of flight (t) for the ball's horizontal motion.

We can use the horizontal distance and the average exit velocity to find the time it takes for the ball to reach the Green Monster wall. The horizontal distance (range) can be determined using the formula:

range = horizontal velocity * time

In this case, the range is given as 94.5m, and the average exit velocity is 41.0m/s. Let's solve for time:

94.5m = (41.0m/s) * t

Simplifying the equation, we have:

t = 94.5m / 41.0m/s

t ≈ 2.31s

Step 2: Find the initial vertical velocity (Viy) at the peak of the trajectory.

Since the ball brushes against the top of the Green Monster, we can assume it reaches its peak at half of the total time of flight (t/2). The vertical motion is influenced by gravity, so the equation to determine the initial vertical velocity is:

Viy = (displacement) / (time)

In this case, the displacement is half the height of the Green Monster, which is 11.34m/2 = 5.67m. The time is half of the total time of flight:

Viy = (5.67m) / (t/2)

Viy = (5.67m) / (2.31s/2)

Viy ≈ 2.46m/s

Step 3: Calculate the horizontal velocity (Vix).

Since the horizontal motion is unaffected by gravity, the horizontal velocity remains constant throughout the ball's trajectory. We can use the horizontal distance and time of flight calculated earlier to find the horizontal velocity:

Vix = (horizontal distance) / (time)

Vix = 94.5m / 2.31s

Vix ≈ 40.95m/s

Step 4: Determine the total initial velocity (Vi) using the Pythagorean theorem.

The total initial velocity of the ball can be calculated using the horizontal and vertical velocities:

Vi = √(Vix^2 + Viy^2)

Vi = √((40.95m/s)^2 + (2.46m/s)^2)

Vi ≈ √(1676.9025m^2/s^2 + 6.0516m^2/s^2)

Vi ≈ √(1682.9541m^2/s^2)

Vi ≈ 41.02m/s

Now we have found the total initial velocity of the ball, which is approximately 41.02m/s.

To determine whether it's a home run, we need to consider the ball's trajectory and the height of the Green Monster. Since the height of the wall is 11.34m and the ball's vertical velocity is 2.46m/s, the ball will not clear the Green Monster and will not result in a home run.

Answers

On particle q1, there is a net force of about +25.6 N, directed to the right.

We must take into account the electrostatic forces between particle q1 and the other two particles, q2 and q3, in order to calculate the net force on particle q1. Coulomb's Law describes the electrostatic force between two charged particles:

F = k * |q₁ * q₂| / r²

F is the force, k is the electrostatic constant (9 x 109 N m2/C2), q1 and q2 are the charges' magnitudes, and r is the distance separating them.

Let's first determine the force between q1 and q2:

F₁₂ = k * |q₁ * q₂| / r₁₂²

F₁₂ = (9 x 10^9 N m²/C²) * |(-29.6 μC) * (+37.7 μC)| / (0.630 m)²

F₁₂ = (9 x 10^9 N m²/C²) * (29.6 x 10^-6 C) * (37.7 x 10^-6 C) / (0.630 m)²

F₁₂ ≈ -7.45 N

The minus symbol denotes an attracting force between q1 and q2, pointing to the left.

Let's next determine the force between q2 and q3:

F₂₃ = k * |q₂ * q₃| / r₂₃²

F₂₃ = (9 x 10^9 N m²/C²) * |(+37.7 μC) * (-10.8 μC)| / (0.315 m)²

F₂₃ = (9 x 10^9 N m²/C²) * (37.7 x 10^-6 C) * (10.8 x 10^-6 C) / (0.315 m)²

F₂₃ ≈ +33.05 N

Positively directed to the right, the force between q2 and q3 is shown by the positive sign.

We must now add all the forces in order to determine the net force on q1:

Net force = F₁₂ + F₂₃

Net force ≈ -7.45 N + 33.05 N

Net force ≈ +25.6 N

Plasma lacks a precise form or volume, much like gas. It completes the empty space. Even though it is in the gaseous form, there is a difference because some of the particles are plasma-ionized.

High-energy particles are free to move around and fill the area they inhabit in the state of matter known as gas.

Neutral atoms or molecules often make up gaseous substances like air.

The ionised gas known as plasma, on the other hand, contains both positively and negatively charged particles.

It develops when a gas is subjected to an intense electric field or heated to incredibly high temperatures.

Plasma is a substance that may be found in stars, lightning, and fluorescent lights. It is also an essential component of many modern technology, like plasma TVs and fusion reactors.

Position and velocity of particles

To find the position and velocity of a particle at a specific time, we can use the equations of motion.

Given:

Initial velocity (u) = 20.4 m/s (east)

Acceleration (a) = -4.40 m/s² (west)

Time (t) = 1.98 s

To find the position (displacement) of the particle at time t, we can use the equation:

s = ut + (1/2)at²

s = (20.4 m/s)(1.98 s) + (1/2)(-4.40 m/s²)(1.98 s)²

s = 40.392 m + (1/2)(-4.40 m/s²)(3.9204 s²)

s = 40.392 m - 8.6914 m

s ≈ 31.7006 m

To find the velocity of the particle at time t, we can use the equation:

v = u + at

v = (20.4 m/s) + (-4.40 m/s²)(1.98 s)

v = 20.4 m/s - 8.712 m/s

v ≈ 11.688 m/s

Therefore, the velocity of the particle at t = 1.98 s is approximately 11.688 m/s to the east.

It is to be constructed in the shape of a hollow ring of mass 48,500 kg. The structures other than the ring shown in the figure have negligible mass compared to the ring. Members of the crew will walk on a deck formed by the inner surface of the outer cylindrical wall of the ring, with radius
r = 115 m.
The thickness of the ring is very small compared to the radius, so we can model the ring as a hoop. At rest when constructed, the ring is to be set rotating about its axis so that the people standing inside on this deck experience an effective free-fall acceleration equal to g. The rotation is achieved by firing two small rockets attached tangentially to opposite points on the rim of the ring. Your supervisor asks you to determine the following: (a) the time interval during which the rockets must be fired if each exerts a thrust of 120 N and (b) the period of rotation of the space station after it has reached its target rotation.
1. Determine the time interval (in hr) during which the rockets must be fired if each exerts a thrust of 120 N.
2. Determine the period of rotation of the space station (in s) after it has reached its target rotation.

Answers

a) Converting the time interval to hours is 0.2 hr

b) The time in seconds is 691468 sec

To determine the time interval during which the rockets must be fired, we can analyze the forces acting on the ring. The rockets provide a tangential force that causes the ring to rotate. This force creates a torque, which results in an angular acceleration. To maintain an effective free-fall acceleration equal to g, the angular acceleration should be equal to g divided by the radius of the ring.

(a) To calculate the time interval, we can use the equation:

θ = ω_i * t + (1/2) * α * t^2

where θ is the angle through which the ring rotates, ω_i is the initial angular velocity, α is the angular acceleration, and t is the time interval. Since the ring starts from rest, ω_i = 0.

The angle θ is given by:

θ = 2π

The angular acceleration α can be calculated using:

α = g / r

where g is the acceleration due to gravity and r is the radius of the ring.

Substituting the given values, we have:

2π = (1/2) * (g / r) * t^2

Solving for t, we get:

t = sqrt((4πr) / g)

Converting the time interval to hours, we divide by 3600:

t = sqrt((4πr) / g) / 3600= 0.2 hr

(b) The period of rotation can be calculated using the equation:

T = 2π / ω

where T is the period and ω is the angular velocity.

Since the angular velocity ω is related to the angular acceleration α by the equation:

ω = α * t

Substituting the values, we have:

T = 2π / (α * t)

Substituting the values of α and t, we get:

T = 2π / (g / r * sqrt((4πr) / g) / 3600)

Simplifying the expression, we have:

T = (2π * r * 3600) / sqrt(4πr * g)= 691468 sec
