uniform circular motion with angular speed
position ...
velocity ...
acceleration ...
A body of mass 9 kg moves in a (counterclockwise) circular path of radius 5 meters, making one revolution every 9 seconds. You may assume the circle is in the xy-plane, and so you may ignore the third component.
Compute the centripetal force acting on the body. (As a vector of 2 components.)
I know the first part of the two components, but I need help solving for the last parts.
Please help!
