You just purchased a brand new car that's supposed to have the best crash rating of all the vehicles on the road in the US. On your way home, someone cut you off on the freeway and you crashed into the crash barrels along the side of the highway. Your car was crunched - but you walked away without an injury. (Hooray!!!). Your best friend is a nurse and they tell you how lucky you are because forces greater than 10 N, will almost always break a bone or cause a head injury. Between the crash barrels and the design of your car, how long was the maximum time of impact for your collision. (You were traveling at 35 m/s, and your car has a mass of 2500 kg.)
