The acceleration due to gravity on Mars is 3.8 m/s2.
a) If the Curiosity rover on Mars drops a tool from a height of 2.25 m, how long does it take to hit the ground?
b) If this tool were dropped on Earth from the same height, how long would it take to hit the ground?
c) From what height would you have to drop the tool on Earth so that the fall-time on both planets would be the same? Neglect air resistance on both Mars and the Earth.
