To solve the problem of calculating the change in momentum of a ball that strikes a wall at an angle of 45 degrees and is reflected at the same angle, we can follow these steps: ### Step 1: Understand the Initial Momentum The momentum of the ball before it strikes the wall is given as \( p = 5 \, \text{kg m/s} \). ### Step 2: Resolve the Momentum into Components Since the ball strikes the wall at an angle of 45 degrees, we need to resolve the momentum into its horizontal and vertical components. ...
