Question

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 :, 0 . 5 N s, 0 . 1 N s, 0 . 3 N s, 1 . 2 N s

MARKS App · Accepted Answer

Mass = 150gm = 150 × 10 - 3 kg F = m a = 150 × 10 - 3 × 20 F = 3 N Impulse = F ∆ t = 3 × 0.1 = 0.3 N s
