Question

An 8-lb weight stretches a spring 4 ft. The spring–mass system
resides in a medium o–ering a resistance to the motion equal to
1.5 times the instantaneous velocity. If the weight is released at
a position 2 ft above its equilibrium position with a downward
velocity of 3 ft > sec, find its position relative to the equilibrium
position 2 sec later.
