<p>A car traveling at 82 km/h strikes a tree. The front end of the car compresses and the driver comes to rest after traveling 0.65 m. What was the average acceleration of the driver during the collision? Express the answer in terms of "g's," where 1.00g = 9.80 m/s^2</p>

<p>Can u guys explain this to me. I do not understand. Thanks guys!!!</p>

2

<p>We know final velocity, initial velocity, and distance. Can you think of an equation that can find acceleration based on that information?</p>

3

<p>how?</p>

<p>vf^2=v0^2+2a(d)?????</p>

4

<p>Use this equation (V-final)^2=(V-inital)^2+2a(Total distance traveled)</p>

5

<p>wow, u're right thanks alot man!!!</p>
