The Displacement of a Particle on a Vibrating String Is $s(t)=2+\frac{1}{13} \sin (18 \pi t)$

Short Answer

The displacement of a particle on a vibrating string is given by the equation $s(t)=2+\frac{1}{13} \sin (18 \pi t)$ where s is measured in centimeter and t in seconds. Find the velocity of the particle after t seconds.
