Avery elastic rubber ball is dropped from a certain height and hits the floor with a downward speed v. since it is so elastic, the ball bounces back with the same speed v going upward. which of the following statements about the bounce are correct? (there could be more than one correct choice.) the magnitude of the ball's momentum was the same just before and just after the bounce. the ball had the same momentum just before and just after the bounce. the ball's momentum was conserved during the bounce. none of the above statements are correct.
