Two buckets of mass m1 = 18.7 kg and m2 = 13.9 kg are attached to the ends of a massless rope, which passes over a pulley with a mass of mp = 7.93 kg and a radius of rp = 0.350 m. assume that the rope does not slip on the pulley, and that the pulley rotates without friction. the buckets are released from rest, and begin to move. if the larger bucket is a distance d0 = 1.55 m above the ground when it is released, with what speed v will it hit the ground?
