Meriam, Kraige & Bolton — Kinematics of Particles: Problem 2_16

2/16 In the final stages of a moon landing, the lunar module descends under retrothrust of its descent engine to within \(h = 5 \text{ m}\) of the lunar surface where it has a downward velocity of \(2 \text{ m/s}\). If the descent engine is cut off abruptly at this point, compute the impact velocity of the landing gear with the moon. Lunar gravity is \(1/6\) of the earth’s gravity.
