The following state model describes the motion of a certain mass connected to a spring, with viscous friction on the surface, where m = 1, c = 2, and k = 5.

 

a. Use the initial function to plot the position x₁ of the mass, if the initial position is 5 and the initial velocity is 3.

b. Use the step function to plot the step response of the position and velocity for zero initial conditions, where the magnitude of the step input is 10. Compare your plot with that shown in Figure 9.5–1.
