Question

The linear momentum of a ball of mass 50 g is 0.5 kg m $s^{- 1} .$ Find its velocity.

Open in App

Solution

Mass of the ball is 50g = 0.05 kg
Momentum = 0.5 kg m/s

As, Momentum = mass x velocity
Velocity = Momentum / mass
= 0.5 kg mps / 0.05 kg
= 10 m/s

Therefore, Velocity of the ball = 10 m/s
