Answer:
Its velocity and acceleration are both nonzero.
Explanation:
The path of the wrench is trajectory while the acceleration due to Moon's gravity is acting on it.
As the velocity follows the path, as soon as it reaches maximum height, the vertical component of velocity is zero but the horizontal component is still there, constant.
In order to have a verified or reliable answer to this question, they should take the watch apart and test the mechanism to see what causes failure.
Answer: Option D
