Question: A 0.17kg billiard ball traveling at a speed of 11m/s strikes the side rail of a pool table at an angle of 60 degree and rebounds at the same speed and angle.
Part A: If the billiard ball is in contact with the rail for 0.020s, what is the magnitude of the average force exerted on the ball?
I want help to find the magnitude of the average force exerted on the ball.
