A bolt of mass 0.2 kg falls from the ceiling of an elevator moving down with a uniform speed of `5 m s^(-1)`. It hits the floor of the elevator (length of the elevator = 5 m) and does not rebound. The amount of heat produced by the impact is (Take `g = 10 m s^(-2)`)

A bolt of mass 0.3 kg falls from the ceiling of an elevator moving down with a uniform speed of 7ms^(-1) . If hits the floors of the elevator (length of the elevator 3m) and does not rebound. What is the heat produced by the impact?

A bolt of mass 0.3 kg falls from the ceiling of an elevator moving down with an uniform speed of 7 m s^-1 . It hits the floor of the elevator (length of the elevator = 3 m) and does not rebound. What is the heat produced by the impact ? Would your answer be different if the elevator were stationary ?
