A car advertisement states that a certain car can selerate from rest to 20 m/s in 7 seconds. Find the car's average acceleration
Answer:
2.86m/s²
Explanation:
[tex]\boxed{average \: acceleration = \frac{change \: in \: velocity}{time} }[/tex]
Car's average acceleration
[tex] = \frac{20 - 0}{7} \\ = 2.86 \: m/ {s}^{2} \: (3 \: s.f.)[/tex]
The reason why the change in velocity over time is average acceleration is because we are finding the total difference in velocity and dividing it against the total duration. This means that the acceleration of the car can vary throughout the 7 seconds (may not be a constant acceleration) but on average, the car's acceleration 2.86m/s², to 3 significant figures.
Change in velocity
= v -v₀
= final velocity -initial velocity
Since the car is at rest at the beginning, the initial velocity (v₀) is 0m/s.
Answer:
Given :-Acceleration = 20 m/sTime = 7 secTo Find :-Average acceleration
Solution :-As we are already knowing that
[tex] \sf Acceleration_{Avg} [/tex] = TA/T
TA = Total acceleration
T = Time
A = 20/7
A = 2.85 m/s²

in what way is Speed related to Kinetic Energy?
Answer:
Explanation:
In order to find kinetic energy, you need information about the velocity. Speed is the magnitude of the velocity.
Kinetic energy is 1/2mv^2
m being mass
v being velocity
The kinetic energy of an object is directly proportional to the speed of the object. If we double the speed of the object then the kinetic energy of the object will increase by a factor of four or four times.
What is Kinetic energy?Kinetic energy is the energy which is present in an object which has because of its motion. If we want to accelerate an object, then we must apply the force of some magnitude. Applying a force, requires us to do some work. After the work has been done, then the energy has been transferred to the object, and the object will be moving with a new constant speed.
Kinetic energy is directly proportional to the mass of the object and to the square of its speed or velocity:
K.E. = 1/2 m × v²
If the mass has the units of kilograms and the velocity of meters per second, then the kinetic energy has units of kilograms-meters squared per second squared.

A toy car is allowed to roll down a ramp during an experiment. While it is on the ramp, gravity acts on the car as an unbalanced force. Which of the following graphs best illustrates the car’s velocity as a function of time while it is on the ramp?
Answer:
When an unbalanced force acts on an object, the motion of the object is changed. If the object is at rest, the force makes it move. If the object is in motion, the force changes its velocity. Any change in velocity is acceleration

if you stung by a honey bee. why we suggest rub with baking soda why?
Answer:
When a bee stings, it injects methanoic acid into the skin which causes immense pain and irritation. Rubbing of baking soda on the sting area gives relief because, being alkaline in nature, baking soda neutralizes the effect of methanoic acid and gives relief.
Explain the centripetal force or Newton's second law...
Answer: a centripetal force is toward the center of curvature, the same as the direction of centripetal acceleration. According to Newton's second law of motion, net force is mass times acceleration: net . For uniform circular motion, the acceleration is the centripetal acceleration
Explanation:
Centripetal force is the force which causes the change in direction of velocity towards the center of the circular motion of an object.
What is Centripetal Force?Centripetal force is any kind of force which causes a change in the direction of velocity of an object which is moving towards the center of the circular motion. The component of this force which is perpendicular to the velocity of the object is the part which results in the centripetal force.
The force of gravity which acts up on a satellite in the orbit is an example of a centripetal force. The friction of the tires of a car which makes a turn that is similarly provides centripetal force on the car.

Zad. 2 W marszobiegu chłopiec przebiegł 900 m w ciągu 205 min, a następnie przeszedł 300m w tym danym czasie. Jaka była średnia prędkość chłopca podczas marszobiegu?
Odpowiedź:
0,049 m / s
Wyjaśnienie:
Biorąc pod uwagę, że:
Dystans biegu = 900m
Czas trwania = 205 minut
Długość przejścia = 300 m
Zajęty czas = 205 minut
Średnia prędkość :
(Przebieg + pokonany dystans) / całkowity czas
Średnia prędkość :
(900 m +. 300 m) / 205 + 205
1200 m / 410 minut
Minuty do sekund
1200 / (410 * 60)
1200/24600
= 0,0487804
= 0,049 m / s
On the way home from school, you notice the speedometer on the car is at 5,200 miles. When you get home, the speedometer reads 5,208 miles. With only this information what value could you calculate?
O Velocity
O Displacement
O Acceleration
O Distance
Answer:
O Distance
Explanation:
With the given information, it is possible to find the distance of the car has traveled on the home from school.
This is possible because distance is the length of path a body covers.
From the given values:
Distance = 5208 - 5200 = 8miles
It is not possible to find the displacement because no direction was given.
Also velocity is not possible since the time frame of travel was not state.

Vivian went on a bicycle trip through Germany with her family. One afternoon, she rode her bicycle along a long flat road at a constant speed for 24 kilometers (km). The ride took her 1.2 hours (h). At what speed did she ride her bicycle?
Answer:
20km/h
Explanation:
Given parameters:
Distance moved = 24km
Time = 1.2hrs
Unknown:
Speed of her ride = ?
Solution:
Speed is the distance covered per unit of time.
So;
Speed = [tex]\frac{distance}{time}[/tex]
Speed = [tex]\frac{24}{1.2}[/tex] = 20km/h

During the course of a trajectory, is the vertical component of the velocity a constant or a changing value? ___________________ If it is a changing value, then describe its changes (increasing, decreasing, or ...)
Answer:
1) Changing value
2) The velocity is decreasing for upward motion and increasing for downward motion due to gravitational force
Explanation:
1) A trajectory is the motion of an object which is being acted upon by specified forces. The flight path of an object in projectile motion is its trajectory
During the course of a trajectory, the vertical component of the velocity, [tex]v_y[/tex], is a changing value
2) The vertical component of the velocity first decreases, during the upward motion, according to the following equation;
[tex]v_y[/tex] = [tex]u_y[/tex] - g·t
Where;
[tex]v_y[/tex] = The vertical component of the velocity after a given time, t
[tex]u_y[/tex] = The initial vertical velocity
t = The time of motion of the trajectory
g = The acceleration due to gravity ≈ 9.8 m/s²
When the vertical velocity of the object decreases to zero, which is the point at which the object reaches the maximum height of its motion, the direction of the vertical motion of the object reverses, and object begins to accelerate and increase its velocity downwards according to the following equation;
[tex]v_y[/tex] = [tex]u_y[/tex] + g·t
Therefore, the velocity of the object is decreasing on its way up, and then increasing on its way down.
