A batsman deflects a ball by an angle of `45^(@)` without changing its initial speed which is equal to `54 km/h`. What is the impulse imparted to the ball ? (Mass of the ball is 0.15 kg)

Explanation

To solve the problem of calculating the impulse imparted to a ball deflected by a batsman at an angle of 45 degrees without changing its initial speed, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Given Data:**
- Initial speed of the ball, \( U = 54 \, \text{km/h} \)
- Mass of the ball, \( m = 0.15 \, \text{kg} \)
- Deflection angle, \( \theta = 45^\circ \)
