In Matlab please do this problem and show the code.

(this figure 2.1)

Use Figure 2.1 to create a transfer function representing a simple spring-mass-damper system. Also consider the standard second-order transfer function equation G(s)=s2+2ns+n2n2 For system parameters m=2(kg) and b=10(N/(m/s)), determine the spring constant value k that yields a critically damped response, or =1. Plot the pole-zero plot for the value of k determined. Also plot for values of k an order of magnitude higher and lower than the determined value. Then plot the response signal for a unit impulse force and unit step force. 1: Basic Spring-Mass-Damper System
