A mass suspended from a spring is pulled down 0.08 m from the equilibrium point and released. It oscillates in simple harmonic motion with a frequency of 5 Hz.
At time t=0t = 0t=0, the mass passes through the equilibrium point.
What is the displacement in metres from the equilibrium point at time ttt?
