A mass of 1 slug, when attached to a spring, stretches it 2feet. It is released from a point 1 foot above the equilibriumposition with a downward velocity of 2 ft/s.
1) Find the equation of motion if the surrounding medium offersa damping force that is numerically equal to 4 times theinstantaneous velocity.
2) Classify the motion as underdamped, overdamped, or criticallydamped.
