Atennis player swings her 1000 g racket with a speed of 9.0 m/s . she hits a 60 g tennis ball that was approaching her at a speed of 25 m/s . the ball rebounds at 36 m/s . (a) how fast is her racket moving immediately after the impact? you can ignore the interaction of the racket with her hand for the brief duration of the collision. (b) if the tennis ball and racket are in contact for 10 ms, what is the average force that the racket exerts on the ball? (c) how does this compare to the ball's weight?

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
