A ball of mass 0 . 2 kg is thrown vertically upward by applying a force by hand. If the hand moves 0 . 2 m while applying the force and the ball goes up to 2 m height further, find the magnitude of the force. Consider g = 10 m s - 2

Question

A ball of mass 0 . 2 kg is thrown vertically upward by applying a force by hand. If the hand moves 0 . 2 m while applying the force and the ball goes up to 2 m height further, find the magnitude of the force. Consider g = 10 m s - 2, 4 N, 16 N, 20 N, 22 N
