PhysicsEasysingle choice

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 $g = 10 m s^{- 2}$

Options:

Answer:

Solution:

$W = ∆ T E$

$F \times 0.2 = m g h$

$F \times 0.2 = 0.2 \times 10 \times (2 + 0.2)$

$F = 22 N$
