question

(a) How much heat energy Is produced by a 5-kg rock that falls a vertical distance of 10 m before it strikes the surface of the earth? Assume that the rock was initially at rest. (b) How much would the temperature of 1 kg of water be raised by the rock striking the earth's surface? (4.19 × 10^3 J of heat energy is required to raise the temperature of 1 kg of water 1°K.)
