Question

# A ball of mass 0.2 k_{b} is thrown vertically up wands by applying a force by hand. If the hand moves 0.2 m while applying the force and the ball goes up to 2m height further, find the magnitude of the force. (Consider g=10ms^{-2} )

- 16 N
- 20 N
- 22 N
- 4 N

## The correct answer is: 22 N
