If an head on collision is inevitable between 2 cars of similar size and weights and self preservation is the main element under consideration, will the driver who brakes hardest be under greater risk of injury?. Will acceleration at time of impact result in less damage to your car and increase the possibilities of your survival. Any theories about this??
The damage done is proportional to the rate of change of momentum (mv), so assuming the cars have the same mass (m) and velocity(v), the one that has the steepest deceleration curve will feel the greater effect...
Keep your foot on the brake. Any deceleration achieved prior to impact will be greatly appreciated. Also this will diminish any acceleration gained after the initial impact by objects that are free to move prior to meeting their final destination.
