A ball moving with a momen - tum of `15 kg ms^(-1) ` strickes against the wall at an angle of `30 ^(@)` and is reflected back with the same momentum at the same angle . Calculte impulse.

Explanation

To solve the problem step by step, we will calculate the impulse experienced by the ball when it strikes the wall at an angle of 30 degrees and reflects back with the same momentum.

### Step 1: Understand the Problem
The ball has an initial momentum of \( P = 15 \, \text{kg m/s} \) and strikes the wall at an angle of \( 30^\circ \). After striking the wall, it reflects back with the same momentum at the same angle.

### Step 2: Break Down the Momentum into Components
We need to resolve the momentum into two components: one parallel to the wall (horizontal component) and one perpendicular to the wall (vertical component).
