the acceleration is always g. If we ignore air drag.

Is always G?

anonymous · Answer

this problem consist air drag. If u ignore it you will see.

anonymous · Answer

Acceleration is always gravity in free fall (-9.81 m/s^2), so the answer for this question would be D. The acceleration is constant everywhere in the trajectory.
