A ball of mass $150 g$ is hit by a force, which acts on it for $0.1 s$ thereby creating an acceleration $20 m s^{- 2}$ . The impulse of force is :

Answer:

Solution:

Mass = 150gm = $150 \times 10^{- 3} kg$

$F = m a = 150 \times 10^{- 3} \times 20$

$F = 3 N$

Impulse = $F ∆ t = 3 \times 0.1 = 0.3 N s$
