At t=0, a body executing simple harmonic motion has displacement 0.03m and velocity 0.40m s−1 directed towards the positive extreme position. The angular frequency of the motion is 10rad s−1.
(i) Determine the amplitude of oscillation and the initial phase.
(ii) Calculate the maximum acceleration of the body.
(iii) Find the displacement and acceleration of the body at t=0.25s.
