A billiard ball strikes the bumper of a pool table and bounces straight back. The billiard ball's mass is 0.210 kg and is originally moving at 2.90 m/s. Following the collision, it bounces straight back at 2.00 m/s (69% of its original speed). The collision lasts 0.0160 s. What is the magnitude of the average force exerted on the ball by the bumper? Hint: what is the sign of the ball's velocity after it bounces straight back? O 82.0 N O 84.2 N O 73.5 N O 78.4 N 64.3 N
