Question
An initially motionless test car is accelerated uniformly to 145km/h in 8.08 seconds before striking a simulated deer. The car is in contact with the faux fawn for 0.875 seconds, after which the car is measured to be traveling at 87.5 km/h. 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?
I was able to answer the other to parts of the question (not mentioned above). Here are the answers I got. I don't know if it will make the question more simple for you to solve or not.
What is the mag. of the accel. of the car prior to the collision? 4.98 m/s^2
What is the mag. of the avg. accel. of the car during the collision? 18.25 m/s^2
Explanation / Answer
A = Vf –Vr
T
A = 145km/hr -0 km/hr
8.08 s
A = 17.94
