6. A 0.25 kg ball bounces off a vertical wall as shown. The speed of the ball just before hitting the wall is 8 m/s and just afterwards is 6 m/s. The collision takes 0.1 sec. a. What is the impulse delivered to the ball? Write in component vector form. y 30° 30 b. What is the average force that the wall exerts on the ball during the collision? Remember the impulse-momentum relation refers to the net force; you will have to take gravity into account when you do your analysis. c. What is the average force that the ball exerts on the wall during the collision?
