When a 0.058 kg tennis ball is served, it accelerates from rest to a speed of 45.0 m/s. The impact with the racket gives the ball a constant acceleration over a distance of 0.440 m. What is the magnitude of the net force acting on the ball?
- What is the average velocity of the ball?
- Over what time period was the ball struck?
- What is the acceleration of the ball?
- What is the net force on the ball?
- If the ball had been heavier, but experienced the same change in velocity, would the applied force have to be greater or lesser than before?
