A force of 108 lbs. will stretch a spring of 4 ft. use this information to compute the K value. There is a damping coefficient of 18 lbs(ft./s). A weight of 96.6 pounds is attached to the spring, moved to 5 ft. above the equilibrium point and released with an initial velocity of 45 ft./s. Do not forget to convert the weigh to mass (slugs) using g=32.2 ft/s^2.
