For a certain dynamic system the state-1wriable equations joT the position x1 and velocity v1 are given below:
=VI 1 i11 = -[-(k1 + k2)x1- bv1 + bx2 + (t), where x 2 ( t) is the input and the output is x 1 . Use the s-opemtor to obtain the input-mdp1d differential equation which relates the output ::r: 1 and the input x2 (t).
