A body that weighs 16 lb. is attached to the end of a spring which is stretched 2 ft. by a force of 100 lb. It is set in motion from a position Â½ foot from the equilibrium position of the spring with an initial velocity of -10 ft/sec.

(a) Find the differential equation that governs the position of the body over time relative to the equilibrium position of the spring.

(b) Solve the differential equation.
