# If the equation of motion of a particle is given by $s = A \cos (wt + 8),$ the particle is said to undergo simple harmonic motion.(a) Find the velocity of the particle at time $t.$(b) When is the velocity 0?

## a. $v=-A \omega \sin (\omega t+\delta)$b. $t=\frac{n \pi-\delta}{\omega}$ Where $n$ is an integer
