Solve Prob. 18–38 if the chain has a mass of 0.8 kg/m. For the calculation neglect the portion of the chain that wraps over the sprocket.

Solve Prob. 18–38

A chain that has a negligible mass is draped over the sprocket which has a mass of 2 kg and a radius of gyration of k_o = 50 mm. If the 4-kg block A is released from rest from the position s = 1 m, determine the angular velocity of the sprocket at the instant s = 2 m.
