Problem-solving strategies for analyzing dynamics problems
Your daredevil friends attach a rope to a 140-kg sled that rests on a frictionless icy surface. The rope extends horizontally to a smooth dead tree trunk lying at the edge of a cliff. Another person attaches a 30-kg rock at the end of the rope after it passes over the tree trunk and then releases the rock— the rope is initially taut. Determine the acceleration of the sled, the force that the rope exerts on the sled and on the rock, and the time interval during which the person can jump off the sled before it reaches the cliff 10 m ahead. There is no friction between the rope and the tree trunk.
