Experiment to prove or disprove answer.

Answer to Problem 52SSC

The ball is accelerating at the certain point due to gravitational acceleration.

Explanation of Solution

Introduction:

The effect of the gravity continuously acts on the object during the entire motion. The effect of the gravity on the object in the upward motion remains negative and become positive for the downward motion.

When the ball throws vertically upward with some velocity, then motion remain in the upward direction till the acceleration of the object is greater than the gravitational acceleration. The ball starts moving downward after certain point.

The velocity of the ball becomes zero at that point. The ball is accelerating at this point despite the zero velocity at this point due to the downward effect of the gravitational acceleration.

Conclusion:

Thus, the ball is accelerating at the certain point due to gravitational acceleration.
