Chapter 4, Problem 64P

GO A particle moves horizontally in uniform circular motion, over a horizontal xy plane. At one instant, it moves through the point at coordinates (4.00 m, 4.00 m) with a velocity of $-5.00\hat{i}$ m/s and an acceleration of $\text{+12}\text{.5}\hat{j}$ m/s². What are the (a) x and (b) y coordinates of the center of the circular path?
