Alarge crate is suspended from the end of a vertical rope. is the tension in the rope greater when the crate is at rest or when it is moving upward at constant speed? if the crate is traveling upward, is the tension in the rope greater when the crate is speeding up or when it is slowing down? in each case, explain in terms of newton’s laws of motion.

Tons?

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
