Homework Help: Acceleration of a crashing car

  1. Sep 14, 2010 #1
    1. The problem statement, all variables and given/known data
    A car traveling 81 km/h strikes a tree. The front end of the car compresses and the driver comes to rest after traveling 0.85 m.

    What was the average acceleration of the driver during the collision?


    2. Relevant equations



    3. The attempt at a solution

    I've converted the speed to meters per second but keep getting stuck when trying to get the equations of the distances.
