6. A ball bounces off a wall. Initially the ball has a horizontal speed of 3.3 m s¹ to the right.After the bounce, the ball has a horizontal speed of 2.8 m s²¹ to the left. The ball has a mass of 0.65 kg, and is in contact with the wall for 7.6 ms. Determine the change in momentum of the ball resulting from the bounce. e(b) Determine the impulse exerted on the ball by the wall. (c) Determine the average force (both magnitude and direction) on the ball by the wall during the bounce. (d) State the average force exerted on the wall by the ball during the bounce. (Briefly)justify your answer.
