Problem
A 250g mass attached to a spring passes through the equilibrium position with speed 0.80ms−1 at t=0. The next instant at which its kinetic energy equals its potential energy is at t=0.35s.
(i) Calculate the angular frequency of oscillation.
(ii) Determine the time period.
(iii) Hence, find the amplitude of motion and the force constant of the spring. (Take π=3.14.)
