Question

Suppose the mass of a fully-loaded module in which astronauts take off from the Moon is 20,000 kg. The thrust of its engines is 70,000 N. The acceleration due to gravity on the moon is 1.51 m/s².

Calculate the magnitude of acceleration in a vertical takeoff from the Moon.

Answer 1

$a=\frac Fm+g=5~\frac m{s^2}.$
