Question

An astronaut standing on a platform on the moon drops a hammer. The hammer falls 6m vertically in 2.7seconds. What is acceleration?

Answer 1

6m Divided by 2.7 Seconds
6/2.7=2.22222222222
2.22222222 Meters per second is end velocity
the change in velocity is Start velocity (0m/s) - end velocity (2.222222222m/s)
So the Change in velocity is 2.222222222m/s
To find acceleration it is Change in velocity (2.2222222m/s)/Time (2.7m/s)
2.222222222222/2.7=0.82304526749
acceleration=0.82304526749 Meters per second Squared
This also would make sense as we already know acceleration is less on the moon.
Answer=0.82304526749m/s ²
