A 16 lb weight is attached to a spring with natural length 5 ft. With the weight attached, the spring mesures 8.2 ft. The weight is initally displaced 3 ft below equilibrium and given an upward velocity of 2ft/sec. The medium resistst the motion with a force of 1 lb for each ft sec of velocity. a. What is the natural frequency of the mass and spring in hertz
