PKRB: Work and Energy

A motor supplies a constant torque or twist of M = 120 lb • ft to the drum. If the drum has a weight of 30 lb and a radius of gyration of k₀ = 0.8ft, determine the speed of the 15-lb carte A after it rises s = 4 ft starting from rest. Neglect the weight of the cord.

v = 49.1 ft/s

v = 29.6 ft/s

v = 26.7 ft/s

v = 44.3 ft/s
