[QUOTE="4play, post: 2856867, member: 7223"] That is correct, but my comment was more intended for the survivability of the collision comparing those speeds. The kinetic energy of the vehicle was not more important than the kinetic energy of the person though. Another thing seat belts do beside keeping you from eating a steering wheel or flying out is they allow you to decelerate with the vehicle. Vehicles are designed to absorb the energy caused by the collision. The kinetic energy drops drastically the longer it takes the vehicle to stop, stopping distance includes the distance the vehicle collapses. Stretch seat belts, and air bags help deceleration a lot too. Since you put up a few examples of kinetic energy for the vehicle, lets look at the energy of the person (unrestrained). We will use a 180 pound person for example. 50 mph - 20,395J (15,043 ft-lb) 85 mph - 58,943J (43,474 ft-lb) 100 mph - 81,583J (60,172 ft-lb) 115 mph - 107,893J (79,578 ft-lb) [/QUOTE]
