A vibrating mass of 0.06 kg has an amplitude of 0.08 m and a time period of 4.0 s. If the motion is simple harmonic, calculate the following for the mass at the equilibrium position a) velocity, b) acceleration, c) kinetic energy.

Definition Definition Special type of oscillation where the force of restoration is directly proportional to the displacement of the object from its mean or initial position. If an object is in motion such that the acceleration of the object is directly proportional to its displacement (which helps the moving object return to its resting position) then the object is said to undergo a simple harmonic motion. An object undergoing SHM always moves like a wave.
