A 16-lb weight is attached to the lower end of a coil spring sus-pended from the ceiling and having a spring constant of 1 lb/ft. The resistance in the spring–mass system is numerically equal to the instantaneous velocity. At t = 0 the weight is set in motion from a position 2 ft below its equilibrium position by giving it a downward velocity of 2 ft /sec. At the end of p sec, determine whether the mass is above or below the equilibrium position and by what distance.
