A 64 lb object stretches a spring 4 ft in equilibrium. It is attached to a dashpot with damping
constant c = 8 lb-sec/ft. The object is initially displaced 18 inches above equilibrium and given a
downward velocity of 4 ft/sec. Find its displacement and time-varying amplitude for t > 0.
2.
C/G A 16 lb weight is attached to a spring with natural length 5 ft. With the weight attached,
the spring measures 8.2 ft. The weight is initially displaced 3 ft below equilibrium and given an
upward velocity of 2 ft/sec. Find and graph its displacement for t> 0 if the medium resists the
motion with a force of one lb for each ft/sec of velocity. Also, find its time-varying amplitude.
