A 10 g lead ball at 300 K is dropped from a height of 10 m. Calculate: (a) the kinetic energy and speed of the ball as it reaches the ground and (b) the temperature rise of the ball if all its kinetic energy is transformed into internal energy as the ball is suddenly stopped after 10 m, given that the specific heat of lead is 125.6 J/kg K and its volume change is negligible.
