An astronaut stands by the rim of a crater on the moon, where the acceleration of gravity is 1.62
m/s2. To determine the depth of the crater, she drops a rock and measures the time it takes for it
to hit the bottom. If the time is 6.3 s, what is the depth of the crater?
Answer:
The depth is 32 m
Explanation:
From the question we are told that
The time is t = 6.3 s
The acceleration due to gravity is
Generally from kinematic equation
Here the u is the initial velocity and the value is 0 m/s
