(Answered) A a steel ball is dropped from a height of three meters

Academics

(a) A steel ball is dropped from a height of three meters onto a concrete floor. It bounces a large number of times but eventually comes to rest. Estimate the ball's rise in temperature.

(b) Suppose the steel ball you used in part (a) is at room temperature. If you converted all its internal energy to kinetic energy, how fast would it be moving? (Give your answer in units of miles per hour. Also, ignore the fact that you would have to create momentum.)

(c) Suppose a nickel-iron meteor falls to the earth from deep space. Estimate how much its temeprature would rise on impact.
