Unformatted text preview: like x(0)=b1*v1(0)/k, since if you consider the equilibrium of the mass M, you get F=kx(0)+b1*v1. You will see that F has to be a constant 10N force so that the velocity source v1(t<0)=1 is achieved. x(0+) must be the same as x(0) for continuity. Note however that xdot(0+) need not be the same as xdot(0) Solution to Part C is clear since you know that for t=0+, Mass M is at rest. The free body diagram of the massless damper should give you the answer. In Part(d) you use the initial conditions in Part (b) to get the solution to the differential equation....
