Question

A particle mass 0.5 kg executing simple harmonic motion, starts its motion from the center position, and its displacement is given by the following equation

y=0.04cos 200Phi(t+1/400). Here the displacement is measured in m & time in s.

(1) find the maximum Velocity?

(2) Find the first phase in seconds?

(3) Find the complete energy?

(4) When its displacement is 0.02 m find the force exerted on the object?
