(a) A baseball weighs 5.13 oz. What is the kinetic energy, in joules, of this baseball when it is thrown by a major league pitcher at 95.0 $\mathrm{mi} / \mathrm{h} ?$ (b) By what factor will the kinetic energy change if the speed of the baseball is decreased to 55.0 $\mathrm{mi} / \mathrm{h} ?$ (c) What happens to the kinetic energy when the baseball is caught by the catcher? Is it converted mostly to heat or to some form of potential energy?
