DIFFERENTIAL EQUATIONS
An 8-lb weight is attached to the lower end of a coil spring
suspended from a fixed support. The weight comes to rest in its
equilibrium position, thereby stretching the spring 6 in. The
weight is then pulled down 9 in. below its equilibrium position and
released at t=0. The medium offers a resistance in pounds
numerically equal to 4x', where x' is the instantaneous velocity in
feet per second. Determine the displacement of the weight as a...

A 128-lb weight is attached to a spring having a spring constant
of 64 lb/ft. The weight is started in motion with no initial
velocity by displacing it 6 in below the equilibrium position and
by simultaneously applying an external force F(t) = 8sin(4t). a.
