A bolt of mass $0.3\; kg$ falls from the celling 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?

A rocket accelerates straight up by ejecting gas downwards. In a small time interval $\Delta t$, it ejects a gas of mass $\Delta m$ at a relative speed $u$. Calculate $KE$ of the entire system at $t + \Delta t$ and $t$ and show that the device that ejects gas does work $=(\frac {1}{2})\Delta mu^2$ in this time interval (negative gravity).
