Question
Using a simple pulley/rope system, a crewman on an Arctic expedition is trying to lower a 6.56 kg crate to the bottom of a steep ravine of 24.7 meters. The 60.9 kg crewman is carefully lowering the crate at a constant speed of 1.50 m/s. Unfortunately, when the crate reaches a point of 13.7 meters above the ground, the crewman slips and the crate immediately accelerates toward the ground dragging the crewman across the ice and toward the edge of the cliff. Assuming no friction, at what speed does the crate hit the ground? Also, assume that the rope is long enough to hit the ground. At what speed does the crewman hit the bottom of the ravine? Assume no air friction.
