Question:

What If? The particle described in Problem 52 (Fig. P8.52) is released from rest at A, and the surface of the bowl is rough. The speed of the particle at B is 1.50 m/s. (a) What is its kinetic energy at B? (b) How much mechanical energy is transformed into internal energy as the particle moves from A to B? (c) Is it possible to determine the coefficient of friction from these results in any simple manner? Explain.
