A particle moves along a circular path over a horizontal xy coordinate system, at constant speed. At time t1 = 4.60 s, it is at point (4.30 m, 6.20 m) with velocity (3.30 m/s) and acceleration in the positive x direction. At time t2 = 13.0 s, it has velocity (–3.30 m/s) and acceleration in the positive y direction. What are the (a)x and (b)y coordinates of the center of the circular path? Assume at both times that the particle is on the same orbit.
