The ladder of the lunar lander was approximately 10ft high. If Neil Armstrong had fallen out of the lander while on the moon, it would have taken him 1.95 s to fall to the lunar surface.
a) Calculate the acceleration due to gravity on the moon?
b) What would Neil's velocity have been at impact with the surface?
c) What would his landing velocity be if instead he fell out of the lander on Earth?
