Step by step solution

01

Motion diagram

* Consider the particle model for the diagram of the motion.

* Represent the rock as a dot and assume the mass of the ball is concentrated into a single point considering the particle model.

* Here the shape or size of the stone does not affect the velocity of it according to the particle model.

* The frame between the dots are increasing as the speed of the ball is increasing while approaching the water under the influence of gravitational acceleration on it.

* The acceleration vector is directed along the motion of the ball when it is just released.

Thus, the motion-diagram of the stone approaching the water is given below:
