Question

An initially motionless car is accelerated uniformly to 145k/h in 8.13 seconds before striking a deer. The car is in contact with the fawn for 0.755 seconds, after which the car is measured to be traveling at 82.0k/h. What is the magnitude of acceleration of the car before the collision? What is the magnitude of 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?
