One ball is initially at rest. On the menu to the right, slide the indicator all the way to the right for a perfectly elastic collision. . For the given masses and initial speeds of the two balls, determine the velocity and momentum after the collision. . Place the two objects one in front of the other, so that they will collide. Fill out all the tables.
