Repeat Problem 2.7 for the system shown in Figure P2.8.
For the system shown in Figure P2.7, the springs are undeflected when x1 = x2 = 0. The input is x2(t), the displacement of the left edge of M2.
a. Write the equation governing the motion of M1.
b. Write an expression for the force f2, positive sense to the right, that must be applied to M2 in order to achieve the displacement x2(t).
