7.51 • A system of two paint buck- ets connected by a lightweight rope is released from rest with the 12.0 kg Figure P7.51 bucket 2.00 m above the floor (Fig. P7.51). Use the principle of con- servation of energy to find the speed with which this bucket strikes the floor. 12.0 kg Ignore friction and the mass of the pulley. 2.00 m 4.0 kg
