Q. The two blocks in the figure are connected by a massless rope that passes over a pulley. The pulley is 17 in diameter and has a mass of 1.9 . As the pulley turns, friction at the axle exerts a torque of magnitude 0.40 .

If the blocks are released from rest, how long does it take the 4.0 kg block to reach the floor?

Q. A box of mass m on a horizontal tabletop is attached by a string of negligible mass to an identical hanging box. the string runs over a frictionless peg .

when the hanging mass is released from rest, the system of two boxes moves with a constant velocity. what is the coefficient of kinetic friction between the box and the tabletop on which it slides?
