Like a baseball bat, a tennis racket has a sweet spot at its center of percussion. If a tennis ball hits this center of percussion, the racket's handle does not accelerate. This is because
A) an impact at the center of percussion exerts no torque about the racket's center of mass and doesn't cause the racket to undergo angular acceleration.
B) the racket's center of mass accelerates backward while its handle rotates forward about its center of mass and the two motions cancel one another at the handle.
C) an impact at the center of percussion transfers no momentum to the racket and doesn't cause the racket to accelerate.
D) the racket's velocity doesn't change when the ball hits its center of percussion.
