3 of 8 r > 0.6/1 INA ||| A mass weighing 6 lb stretches a spring 2 in. If the mass is pushed upward, contracting the spring a distance of 4 in and then set in motion with a downward velocity of 4 ft/s, and if there is no damping and no other external force on the system, find the position u of the mass at any time t. Determine the frequency (wo), period (T), amplitude (R), and phase (8) of the motion. NOTE: Enter exact answers. Use t as the independent variable. u(t) wo = 8√√3 rad/s 7T T = 4√√√3 S R = 8 = 6 5/6 ft rad
