A spiring is stretched 1.5 in by a 4 lb. weight. Let the weight be pulled down 3 in. below the equilibrium level and then released. find the equation of the motion if there is an outside force F(t) = 8sin16t acting upon the spring.
A 32 lb weight is attacked to the end of a spring with spring constant k=24 lb/ft/ If the resistive force is 10 dx/dt, find out the displacement of the mass if it is released with no intial velocity from a position of 6 in above the equilibrium po
