If the equation of motion of a particle is given by s(t)=A\cos(wt+d) ,
the particle is said to undergo * simple harmonic motion*.
Assume 0\leq d <\pi .

(a) Find the velocity of the particle at timet .

(b) What is the smallest positive value oft for which the velocity is 0? Assume that w and d are positive.

(a)v(t) =

(b)t=
