A billiard ball strikes and rebounds from the cushion of a pool table perpendicularly. The mass of the ball is 0.38 kg. The ball approaches the cushion with a velocity of +2.50 m/s and rebounds with a velocity of -1.80 m/s. The ball remains in contact with the cushion for a time of 3.00 × 10-3 s. What is the average net force (magnitude and direction) exerted on the ball by the cushion? F =...... (number) ....... the tolerance is...
