If the equation of motion of particle is given by s=A cos(wt+sigma), the particle is said to undergo simple harmonic motion.
a) find the velocity of the particle at time t.
s'(t)=
b)when is the velocity 0? (use n as the arbitrary integer.)
t=
The velocity is given by v = -w*A*sin(wt+sigma)
The velocity is zero when wt + sigma = n*pi or: t = (n*pi - sigma)/w
.
