Question:
A particle starts from rest and moves in a straight-line so that, t seconds after leaving a fixed-point O, its displacement, s metres, is given by s = 2 – 2 cos 2t.
a. Find an expression for the velocity and the acceleration of the particle in terms of t.
b. Find the time when the particle first comes to rest and its distance from O at this instant.
