Question

Neil Armstrong dropped a hammer on the moon. If it took 4 seconds to fall and the final speed was 8 m/s, what is the acceleration due to gravity on the moon?

A. 9.8 m/s2
B. 4 m/s2
C. 32 m/s2
D. 2 m/s2

Answer 1

Answer:

Acceleration due to gravity on moon = 1/6 × acceleration due to gravity on earth

= 1/6×9.8

= 1.6 m/s²

= 2m/s² ( approx.)
