Question

two rubber balls travel towards a wall with the same speed. one of the rubber balls has been dipped in super glue, and sticks to the wall. the other ball bounces off and heads in the opposite direction with the same speed. if each ball is in contact with the wall of the same amount of time, which ball exerts more force on the wall? what is the ratio of the forces between the two cases (how many times greater is one force compared to the other?) explain.
