A1700 kg car moving at 5.1 m/s is initially traveling north in the positive y direction. after completing a 90° right-hand turn to the positive x direction in 4.1 s, the inattentive operator drives into a tree, which stops the car in 240 ms. what is the magnitude of the impulse on the car (a) due to the turn and (b) due to the collision? what is the magnitude of the average force that acts on the car (c) during the turn and (d) during the collision? (e) what is the angle between the average force in (c)and the positive x direction?
