A car traveling 85 km/h strikes a tree. The front end of the car compresses and the driver comes to rest after traveling 0.80m. What is the average acceleration of the driver during the collision? Express the answer in terms of "g's", where 1.00g= 9.80m/s^2
The answer is 36 g's. I have no idea how I am not getting that. Any tips on setting this up?

Best ResponseYou've already chosen the best response.0\[v_f^2=v_i^2+2ad\]in this case the acceleration is in the opposite direction as the initial velocity, and the final velocity is zero\[0=v_i^22ad\to a=\frac{v_i^2}{2d}\]divide this by g and you should get your answer.

Best ResponseYou've already chosen the best response.0You have to care unit. car velocity unit km/h , g unit m/sn^2 and driver comes 0.80m
