Part II : 60 points - (Each question is 15 points) 11. A car of mass 1,410 kg collides with a wall and rebounds as shown in the figure. The initial velocity of the car is Vo = 15.1 m/s and the final velocity is vy = -2.32 m/s. The collision lasts for 0.141 sec. a) (6 pts) What is the change in momentum of the car? Before After b) (3 pts) What is the impulse delivered to the car due to the collision? c) (6 pts) What is the (i) magnitude and (ii) direction of the average force exerted on the car by the wall
