Explain why we will use thecylindrical

coordinate.

Determine the cylindrical

components of the velocity and

acceleration of the horse when t $=2$

s$.$ A horse on the merry$-$go$-$round

moves according to the equations r

$=8$ ft$,=(0\mathrm{.}6$t$)$ rad, and z $=(2$

cos$($theta$))$ ft$,$ where t is in

seconds.
