Question
An object moves along the $x$ -axis so that its position at any time $t \geq 0$ is given by $x(t)=s(t) .$ Find the velocity of the object as a function of $t$.$$s=\cos \left(\frac{\pi}{2}-3 t\right)$$
Step 1
We need to find the velocity function, which is the derivative of the position function with respect to time $t$. Show more…
