Question: one way to measure g on another planet or moon...

Question details

One way to measure g on another planet or moon by remote sensing is to measure how long it takes an object to fall a given distance. A lander vehicle on a distant planet records the fact that it takes 4.00 s for a ball to fall freely 11.54 m , starting from rest.

A-What is the acceleration due to gravity on that planet? Express your answer in m/s2.

B-What is the acceleration due to gravity on that planet? Express your answer in earth g’s.

C-How fast is the ball moving just as it lands?
