Question Number 31144 by NECx last updated on 03/Mar/18

A mass oscillating on a spring  has amplitude of 1.2m and a  period of 2.0s.  (a)Deduce the equation for the  displacement x if the timing starts  at the instant where the mass  has its maximum displacement.  b)calculate the time interval  c)the velocity at this position.
