A batsman deflects a ball by an angle of `90^(@)` without changing its initial speed, which is equal to 54 km/hr. What is the impulse to the ball ? Mass of the ball is 0.15 kg.

Explanation

To solve the problem of finding the impulse imparted to the ball when it is deflected by an angle of 90 degrees, we can follow these steps:

### Step 1: Understand the given data
- Initial speed of the ball, \( v = 54 \) km/hr
- Mass of the ball, \( m = 0.15 \) kg
- Angle of deflection, \( \theta = 90^\circ \)

### Step 2: Convert the speed from km/hr to m/s
