A cricket ball of mass 150 kg is moving with a velocity of `12 m//s` and is hit by a bat so that ball is turned back with a velocity of `20 m//s` . The force of the blow acts for 0.01 s on the ball . Find the average force exerted by the bat on the ball.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Identify the given values
- Mass of the cricket ball (m) = 150 kg
- Initial velocity (u) = 12 m/s (moving in one direction)
- Final velocity (v) = -20 m/s (moving in the opposite direction after being hit)
- Time of contact (t) = 0.01 s
