# A mass of 55 grams stretches

by | Sep 15, 2021 | Homework Help

A mass of 55 grams stretches a spring by 7 cm. (Note that this means the forces balance, and thusmy 2 k3: where m. = 55 grams is mass, 9 = 981 cmis is acceleration due to gravity, k is the spring constant, and a: = 7 cm is the displacement.)The mass is set in motion from this equilibrium position with an initial downward velocity of 14 cmis, and there is nodamping. Find the position at. (in cm} of the mass at any time t (in 5). (Assume that position is measured upward from the equilibrium position.) u?) = El Find the frequency (in radians per second), period (in seconds), and amplitude (in cm) of the motion. Frequency isPeriod is Amplitude is
