Step Response of a Second-Order Model

Consider the following model:

$\frac{X(s)}{F(s)}=\frac{cs+5}{10s^2+cs+5}$

a. Plot the unit-step response for c = 3 using the time span selected by MATLAB.
b. Plot the unit-step response for c = 3 over the range 0 ≤ t ≤ 15.
c. Plot the unit-step responses for c = 3 and c = 8 over the range 0 ≤ t ≤ 15. Put the plots on the same graph.
d. Plot the step response for c = 3, where the magnitude of the step input is 20. Use the time span selected by MATLAB.
