Question
Consider the situation where a lunar lander is making a descent to a base
located on the surface of the Moon. At first it is undergoing a slow
controlled descent due to the retro-thrust of its descent engine but when it
is 2.5 m above the surface of the moon, with a downward speed of 0.5 m/
s, the engine is cut off... Calculate the speed of the lander just as it
touches the surface of the moon (use fact that g 1.6 m/s² on the moon).
