Can someone help me with physics? I tried working this problem out on my own but the answers came out wrong.
An initially motionless test car is accelerated uniformly to 125 km/h in 8.28 seconds before striking a simulated deer. The car is in contact with the faux fawn for 0.395 seconds, after which the car is measured to be traveling at 65.5 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 i did first was i converted 125 km/h to m/s and same goes with 65.5 km/h to m/s. initial velocity would be zero so i divided the first velocity by 8.28 sec to get the answer but my answer came out wrong. where did i make the mistake?
