Problem 5 - Rigid Body Kinetics (25 pts) The sheave of 400-mm radius has a mass of 50 kg and a radius of gyration of 300 mm. The heave and its 100-kg load are suspended by the cable and the spring, which has a stiffness of 1500 N/m. If the system is released from rest with the spring initially stretched 100 mm, determine the velocity of O after it has dropped 50 mm. 400 mm 100 kg
