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.
