I just need to find the amplitude
(5 points) A mass weighing 5 lb stretches a spring 3 in. If the mass is pushed upward, contracting the spring a distance of 1 in, and then set in motion with a downward velocity of 2 ft/s, and if there is no damping, find the position, y, of the mass at any time t. Y = Find the period, frequency, and amplitude of the motion. period = amplitude = ft
