Chapter 5, Problem 35(choose chapter or problem)
A mass m is attached to the end of a spring whose constant is k. After the mass reaches equilibrium, its support begins to oscillate vertically about a horizontal line L according to a formula h(t). The value of h represents the distance in feet measured from L. See Figure 5.1.21. (a) Determine the differential equation of motion if the entire system moves through a medium offering a damping force that is numerically equal to b(dxdt). (b) Solve the differential equation in part (a) if the spring is stretched 4 feet by a mass weighing 16 pounds and b 2, h(t) 5 cos t, x(0) x(0) 0. (b
