position of the mass at any time t ...
centripetal force ...
A body of mass 12 kg moves in a (counterclockwise) circular path of radius 11 meters centered at the origin, making one revolution every 10 seconds. We assume the circle is in the xy-plane, and so the third component may be ignored. At time t=0 the body is in the rightmost position (position with the largest x).
A. Compute the centripetal force acting on the body at time t.
B. Compute the magnitude of that force. = 52.11
i found part B, but i have no idea how to solve part A
