Magnitude and Force

A body of mass 3 kg moves in a (counterclockwise) circular path of radius 9 meters, making one revolution every 12 seconds. You may assume the circle is in the xy-plane, and so you may ignore the third component.


(a) Compute the centripetal force acting on the body.

(b) Compute the magnitude of that force.


I was able to get part (b) = 7.402203301, which was correct, but I do not know how to solve part a.
