Using a simple pulley/rope system, a crewman on an Arctic expedition is trying to lower a 5.91kg crate to the bottom of a steep ravine of height 22.1 meters. The 45kg crewman is being careful to lower the crate at a constant speed of 1.5 m/s. Unfortunately, when the crate reaches a point of 12.3 meters about the ground, the crewman sliips and the crate immediately accelerates toward the ground, dragging the crewman across the ice and toward the edge of the cliff. If we assume the ice is perfectly slick (that is, no friction between the crewman and the ice once he slips and falls down), at what speed will the crate hit the ground? Assume also that the rope is long enough to allow the crate to hit the ground before the crewman slides over the side of the cliff. Also, at what speed will the crewman hit the bottom of the ravine? Assume no air friction. Both answers in m/s.
