A mass weighing 11 lb stretches a spring 4in. The mass is pulled down an additional 3 in and is then set in motion with an initial upward velocity of 5 ft/s. No damping is applied.
(a) Determine the position u of the mass at any time t. Use 32 ft/s² as the acceleration due to gravity. Pay close attention to the units.
(b) Determine the period, amplitude and phase of the motion.
