Detailed Solution

Rohan and Abdul are friends. They are playing with a ball in the garden, Rohan throws the ball in the air to be caught by Abdul, and Abdul after catching the ball does the same. The velocity of the ball decreases when it is thrown vertically upwards.
When the ball is thrown upwards, the velocity of the ball decreases. This is because the gravitational pull of the earth is downwards and it is against the direction of the force of the ball. The gravitational pull of the Earth is a force that provides acceleration to the ball downwards towards the Earth, in the opposite direction of its initial velocity. At the topmost point, the velocity of the ball becomes zero. Thus, the velocity of the ball that is vertically thrown upwards decreases.
