5. (3 pts) The 0.5-kg ball strikes the wall with the incoming horizontal velocity ($v_1$ = 15 m/s) and bounces off with an angle $\theta$ = 25° and the final velocity ($v_2$ = 30 m/s). Determine the magnitude of the net impulse of the wall on the ball in [N\cdot s]. Neglect the size of the ball and the impulse produced by the weight of the ball.

(10 marks total) Consider the linear time-invariant discrete-time system described by the difference equation: \begin{equation} y[n] - \frac{1}{4}y[n - 2] = 2x[n] - x[n - 1] \end{equation} (a) [5 marks] Determine the zero-input response of the system. Assume $y[-1] = 1$ and $y[-2] = 3$. (b) [5 marks] Verify your answer by computing the first three terms of the zero-input response using the iterative/recursive method.
