A 15.5 kg mass vibrates in simple harmonic motion with a frequency of 7.9 Hz. It has a maximum displacement from equilibrium of +14 cm at time, t = 0.00 s. What is the position of the mass at time, t = 0.35 s?
And when an object vibrates in simple harmonic motion in the vertical direction, where does its minimum speed occur? (at the highest endpoint, lowest endpoint, at both end points or at the equilibrium endpoint?)
