A batsman hits back a ball straight in the direction of the bowler without changing its initial speed of `12 ms^(-1)` . If the mass of the ball is 0.15 kg , determine the impulse imparted to the ball . (Assume linear motion of the ball).

Explanation

To determine the impulse imparted to the ball when a batsman hits it back, we can follow these steps:

### Step 1: Understand the Initial and Final Conditions
- The initial speed of the ball (before being hit back) is given as \( u = 12 \, \text{m/s} \).
- After being hit back, the ball travels in the opposite direction with the same speed, so the final speed (after being hit back) is \( v = -12 \, \text{m/s} \) (the negative sign indicates the change in direction).

### Step 2: Calculate the Initial Momentum
- The mass of the ball is given as \( m = 0.15 \, \text{kg} \).
