5)A mass of 100 grams stretches a spring 98 cm in equilibrium. A
dashpot attached to the spring supplies a damping force of 600
dynes for each cm/sec of speed. The mass is initially displaced 10
cm above the equilibrium point before the mass is attached, and
given a downward velocity of 1 m/sec. Find its displacement for
t>0.
