If you have two objects moving at the same velocity, would the object with bigger mass have higher or lower kinetic energy?
Answers
Answer:
The kinetic energy of a moving object is directly proportional to its mass and directly proportional to the square of its velocity. This means that an object with twice the mass and equal speed will have twice the kinetic energy while an object with equal mass and twice the speed will have quadruple the kinetic energy.

How much work is done on a pumpkin with a force of 24 newtons when you lift it 15 meters? *
Answers
Answer:
I'm not that busy solving but I'll tell you the formula that Force x distance is equal to work done
The work is done on a pumpkin when we lift it by 15 m with 24 N is 360 J
What is Work ?Work done is the amount energy gained (loosed) in bringing the body from initial position to final position. It is denoted by W and its SI unit is joule(J).
i.e. Work(W) is force(F) times displacement(s).
W=F× s
When a body is displaced with 1 newton of force by 1 m, then we can say that work has been done on the body by 1 joule.
Writing for it's dimension,
W=F× s
Force has dimension [L¹ M¹ T²]
Displacement has dimension [L¹]
multiplying both the dimensions Force and Displacement
we get,
dimension of Work [L² M¹ T²]
According to newton's second law of motion,
Force(F) is mass(M) times acceleration(a).
i.e. F=ma
Given,
Force = 24 N
Displacement = 15 m
W=F.s= 24*15 = 360 J
Hence work done on pumpkin is 360 J

Show that liquid pressure is directly
proportional to height of liquid in a vessel.
Answers
Answer:
P=F/A where F is the weight of the water and A is the area on which it is resting. The weight of the water is mg. The mass of the water is dv where d is the density and v is the volume. Finally, the volume of the water in a vessel is equal to the area of the base of the vessel times the height of the vessel. (v=Ah)
Plugging everything in we get:
P = dAhg/A
So
P=dhg
So we have shown that liquid pressure is directly proportional to height of liquid in a vessel.

A ball is launched with an initial horizontal velocity of 10.0 meters per second. It takes 500 milliseconds for the ball to reach its maximum height.
Answers
Answer:
maximum horizontal distance = 10m
initial vertical velocity of the ball = 4.9m/s
Explanation:
Complete question
A ball is launched with an initial horizontal velocity of 10.0 meters per second. It takes 500 milliseconds for the ball to reach its maximum height.
Determine the maximum horizontal distance that the ball will travel.
Calculate the initial vertical velocity of the ball.
Maximum horizontal distance x is expressed as;
x = vT
T is total time of flight
T = 2t
Hence x = 2vt
v is the velocity
t is the time
Given
v = 10.0m/s
time t = 500ms = 0.5s
Horizontal distance = 2 * 10 * 0.5
Horizontal distance = 20 * 0.5
Horizontal distance = 10m
Hence the maximum horizontal distance that the ball will travel is 10m
To get the initial horizontal distance, we will use the equation of motion
v = u - gt
T maximum height, v = 0
Substitute
0 = u - 9.8(0.5)
-u = - 4.9
u = 4.9m/s
Hence the initial vertical velocity of the ball is 4.9m/s

A pumpkin is thrown horizontally off of a building at a speed of 2.5 — and travels a horizontal distance of
12 m before hitting the ground. We can ignore air resistance.
What is the vertical velocity when it hits the ground
Answers
Answer:
Explanation:
This is a missile throwing exercise, let's find the distance
x = v₀ₓ / t
t = v₀ₓ / x
let's calculate
t = 2.5 / 12
t = 0.2083 s
as time is a scalar this is the same value for descends to the ground
y = v_{oy} t - 1/2 g t²
we calculate
v_y = 0 - 9.8 0,2083
v_y = - 2.04 m / s
the negative sign indicates that the speed is down

Is there gravitational force between two students sitting in a classroom?
If so, explain why you don't observe any effects of this force.
Answers
Answer:
Yes.
Explanation: the magnitude of the force is extremely small because the masses of the students are small relative to Earth's mass.
The gravitational force between two students sitting in classroom exists but its effect are not visible because the distance between these students is very very very small.
We have two students sitting in a classroom.
We have to investigate whether or not there is gravitational force between these two students.
State Newtons law of Gravitation.Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Mathematically -
[tex]$F=\frac{GMm}{r^{2} }[/tex]
According to the question, we have - Two students sitting in a classroom.
Take a close look and you will identify that the distance between any two students in classroom is very small. Gravitational force is also the weakest force since the value of Universal gravitation constant (G) = 6.674 x [tex]10^{-11}[/tex] [tex]m^{3}kg^{-1}s^{-2}[/tex] is very small. Moreover, the force of gravitation is inversely proportional to square of distance between two bodies -
[tex]$F \alpha \frac{1}{r^{2} }[/tex]
This will make the gravitational force even more weak. This is the main reason why you don't observe any effects of this force. The gravitational force exists between any two bodies that have mass and energy, but its magnitude might depend upon other factors to.
Hence, the gravitational force between two students sitting in classroom exists but its effect are not visible because the distance between these students is very very very small.

What is the speed of a 200-kilogram car that is driving with 2000 joules of kinetic energy? (SHOW ALL WORK)
Answers
Answer:
v ≈ 4.47
Explanation:
The Formula needed = KE = [tex]\frac{1}{2}[/tex] m v²
Substitute with numbers known:
2000J = [tex]\frac{1}{2}[/tex] × 200kg × v²
Simplify:
÷100 ÷100 (Divide by 100 on both sides)
2000J = 100 × v²
[tex]\frac{2000J}{100}[/tex] = v²
20 = v²
√ √ (Square root on both sides)
√20 = √v²
4.472135955 = v (Round to whatever the question asks)
v ≈ 4.47 (I rounded to 2 decimal places or 3 significant figures, as that is what it usually is)
