Answer:
1) 130, 000 J
2) 1 J
Explanation:
1)
Work done is product of force in Newtons and distance in meters
W=Fd
Given an average force of 5,200 N and distance of 25 m then we evaluate that
Work done=5200*25=130, 000 Nm or Joules
2)
Similarly, for the second question, given force of 1N and distace of 1 m then the work done will be
W=1*1=1 J
Answer:
Its velocity and acceleration are both nonzero.
Explanation:
The path of the wrench is trajectory while the acceleration due to Moon's gravity is acting on it.
As the velocity follows the path, as soon as it reaches maximum height, the vertical component of velocity is zero but the horizontal component is still there, constant.
Answer:
If you’re going to be shooting a lot, get a surplus flak jacket. This isn’t a bulletproof vest, it just stops fragmentation or shrapnel. More importantly, it absorbs shock. You can fire a 12 gauge shotgun all day long and you won’t feel sore at all.

The potential energy of the model will be the greatest at point C while it will be the least at point E. Option B and D are correct.
<h3>
What is potential energy?</h3>
The potential energy of an object is due to its position. It can be given as the formula,
Where,
- potential energy
- mass
- gravitation acceleration
- height
From the formula since the mass and gravitation acceleration is constant, the potential energy of the model will depend upon the height only.
The potential energy will be greatest at point C because the relative position of the ball is the highest from the earth.
The potential energy will be lowest at point E because the height of the ball is the least in this position.
Therefore, the potential energy of the model will be the greatest at point C while it will be the least at point E.
