A particle moves along a circular path over a horizontal xy coordinate system, at constant speed. At time t1 = 4.00 s, it is at point
(5.00 m, 6.00 m) with velocity (3.00 m/s)j and acceleration in the positive x-direction. At time t2 = 10.0 s, it has velocity (−3.00 m/s)i and acceleration in the positive y-direction. What are the (a) x and (b) y coordinates of the center of the circular path if t2 ‒ t1 is less than
one period?

Atennis player used a tennis racket to hit a tennis ball with a mass of 0.25 kg with a force of 5.25 newtons. how does the force the tennis racket exerted on the tennis ball compare with the force the tennis ball exerted on the tennis racket? a. the force of the tennis racket on the tennis ball is equal in magnitude and opposite in direction to the force the tennis ball exerted on the tennis racket. b. the force of the tennis racket on the tennis ball is equal in magnitude and in the same direction as the force the tennis ball exerted on the tennis racket. c. the force of the tennis racket on the tennis ball is less in magnitude and in the same direction as the force the tennis ball exerted on the tennis racket. d. the force of the tennis racket on the tennis ball is greater in magnitude and opposite in direction as the force the tennis ball exerted on the tennis racket.
