(choose chapter or problem)

What If? The block of mass m 5 200 g described in (Fig. P8.43) is released from rest at pointA, and the surface of the bowl is rough. The blocksspeed at point B is 1.50 m/s. (a) What is its kineticenergy at point B? (b) How much mechanical energyis transformed into internal energy as the block movesfrom point A to point B? (c) Is it possible to determinethe coefficient of friction from these results in any simplemanner? (d) Explain your answer to part (c).
