In a crash test, a car of mass 1500 kg collides with a wall and rebounds as in the figure. The initial and final velocities of the car are vo = −15.0 m/s and v = 2.6 m/s respectively. If the collision lasts for 0.15 s find (A) the impulse delivered to the car due to the collision and (B) the magnitude and direction of the net force exerted on the car.
