일반물리학 1 — Motion in Two and Three Dimensions: Problem 64

64 A particle moves horizontally in uniform circular motion, over a horizontal $xy$ plane. At one instant, it moves through the point at coordinates $(4.00 \text{ m}, 4.00 \text{ m})$ with a velocity of $-5.00\hat{i} \text{ m/s}$ and an acceleration of $+12.5\hat{j} \text{ m/s}^2$. What are the (a) $x$ and (b) $y$ coordinates of the center of the circular path?
