Two blocks are attached to either end of a light rope that passes over a light, frictionless pulley suspended from the ceiling. One block has mass 8.00 kg, and the other has mass 6.00 kg. The blocks are released from rest. (a) For a 0.200 m downward displacement of the 8.00 kg block, what is the change in the gravitational potential energy associated with each block? (b) If the tension in the rope is T, how much work is done on each block by the rope? (c) Apply conservation of energy to the system that includes both blocks. During the 0.200 m downward displacement, what is the total work done on the system by the tension in the rope? What is the change in gravitational potential energy associated with the system? Use energy conservation to find the speed of the 8.00 kg block after it has descended 0.200 m.

As usual, Hampus is out cycling. He is driving at 30.0 km/ h when he comes to a small hill that is 11 m high and 350 m long. Hampus and the bike weigh 95 kg together. a) What kinetic energy does Hampus have just before the hill? b) How much extra energy must Hampus produce to maintain a constant speed (30.0 km/ h) throughout the hill? c) How long does it take him to drive up the hill? d) What effect must he develop on the hill? Once at the top of the hill, the ground is flat. Hampus is tired and stops pedaling. After 12s the cycle stops. e) How big is the coefficient of friction? You can assume that is constant throughout the deceleration and that it includes both drag and rolling resistance.
