Question: Two buckets of mass m1 = 17.1 kg and m2 = 12.3 kg are attached to the ends of a massless rope, which passes over a pulley with a mass of mp = 9.33 kg and a radius of rp = 0.150 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 = 1.85 m above the ground when it is released, with what speed v will it hit the ground?
A 1.7kg book is lying on a 0.80m -high table. You pick it up and place it on a bookshelf 2.3m above the floor. During this process, how much work does gravity.
A person is doing strength training of knee extensor muscles. He sits on a bench, with a weight attached to his ankle. In what position of the leg will the gravitational torque about the knee joint be maximum?
the coefficient of kinetic friction between the table and the block is 0.320. Sand is gradually added to the bucket until the system just begins to move. Compute acceleration of the motion.
