Chapter , Problem 75(choose chapter or problem)
A 1200-kg car is being raised over water by a winch. At the moment the car is above the water (Figure 9-56), the gearbox breaks, allowing the winch drum to spin freely as the car falls. During the cars fall, there is no slipping between the (massless) rope, the pulley wheel, and the winch drum. The moment of inertia of the winch drum is and the moment of inertia of the pulley wheel is The radius of the winch drum is and the radius of the pulley is Assume that the car starts to fall from rest. Find the speed of the car as it hits the water.
