A body moving with simple harmonic motion, has an amplitude of 1 m and period of oscillation is 2 seconds. Find the velocity and acceleration of the body at $\mathrm{t}=0.4$ second, when time is measured from (b) the extreme position. ( $\mathbf{6} \boldsymbol{\times} \mathbf{1 0} \boldsymbol{=} \mathbf{6 0}$ Marks)
Explanation
The velocity and acceleration of the body are calculated using the equations of simple harmonic motion. The velocity is given by v = Aωsin(ωt), and the acceleration is given by a = Aω^2cos(ωt).
