An initially motionless test car is accelerated uniformly to 125 km/h in 7.83s before striking a simulated deer. The car is in contact with the faux fawn for 0.515s, after which the car is measured to be traveling at 76.5 km/h. What is the magnitude of the acceleration of the car before the collision? What is the magnitude of the average acceleration of the car during the collision? What is the magnitude of the average acceleration of the car during the entire test, from when the car first begins moving until the collision is over?
