A cricket ball of mass’m’ is thrown upward with some initial speed

1.	A cricket ball of mass’m’ is thrown upward with some initial speed. If the air resistance is neglected, what forces are acting on the ball when it reaches (a) half its maximum height and (b) its maximum height?
Answer» The forces which are acting on the ball thrown vertically upward: a) At half of its maximum height: 1. The remaining force which acts vertically upwards (some force that we applied is utilized in reaching half of maximum height). 2. The gravitational force downwards. b) At maximum height: Gravitational force acts downward direction (The applied force is completely utilized in reaching maximum height)

Answer»

The forces which are acting on the ball thrown vertically upward:

a) At half of its maximum height:

1. The remaining force which acts vertically upwards (some force that we applied is utilized in reaching half of maximum height).

2. The gravitational force downwards.

b) At maximum height: Gravitational force acts downward direction (The applied force is completely utilized in reaching maximum height)
