A professional golfer strikes a golf ball with his driver, imparting a momentum of $15 k g . m / s$ on the ball. The golf ball strikes a wall and it remains in contact for $0.0025$ seconds before it bounces at the same velocity with which it struck the wall. Calculate the momentum of the golf ball ?

Solution

The correct option is E $15 k g . m / s$
The momentum of a body is defined as $\to p = m \to v$ .
Since before and after striking the wall, the speed and the mass of the ball remains the same, the momentum also remains the same $= 15 k g . m / s$
