A particle moves horizontally in uniform circular motion, over a horizontal xy plane. At one instant, it moves through the point at coordinates (7.00 m, 7.00 m) with a velocity of -5.00 i m/s and an acceleration of -12.0 j m/s2. What are the coordinates of the center of the circular path? I figured you'd have to find the radius and then it would be a simple problem but I was wrong. How is this done.
