steel ball with a mass of 40.0g is dropped from a height of 2.00 m onto a horizontal steel slab. The ball rebounds to a height of 1.60m. A) Calculate the impulse delivered on the ball during the impact. B) If the ball is in contact with the slab for 2 ms find the average force on the ball during the impact?
