A ball of 0.20kg hits a wall at an angle of `45^(@)` with a velocity of `25 ms^(-1)`. If the rebounds at `90^(@)` to the direction of incidence, calculate the change in momentum of the ball.

Explanation

To solve the problem, we will calculate the change in momentum of the ball when it hits the wall and rebounds. Here are the steps:

### Step 1: Identify the given values
- Mass of the ball (m) = 0.20 kg
- Initial velocity (v_i) = 25 m/s (at an angle of 45 degrees)
- Final velocity (v_f) = 25 m/s (rebounded at 90 degrees to the direction of incidence)

### Step 2: Break down the initial and final velocities into components
