Prob 4 We examine the following mechanical system: F m The input to the system is defined as the force $F$ applied to the mass. The output of the system is defined as $y = \begin{bmatrix} z & \dot{z} \end{bmatrix}^T$ a. Write the equations of motion describing the dynamics of the system, what is the order of the system? b. Write a physical implementation of the system and compute its impulse response c. Examining $m = 1$, we sample the system at constant intervals $T_s = 1$[sec], find an equivalent discrete system. d. Examining $y(0) = \dot{y}(0) = 0$ and $u(t) = \begin{cases} 1, & 0 \le t < 2 \\ 0, & t \ge 2 \end{cases}$ Compute the response of both the continuous system and the equivalent discrete system. Is the response of the continuous system identical to that of the discrete one at the sampling times? Please explain.
