A person who is properly constrained by an over-the-shoulder seat belt has a good chance of surviving a car collision if the deceleration does not exceed about 30 "'s".
Assuming uniform deceleration of this value, calculate the distance over which the front end of the car must be designed to collapse if a crash brings the car to rest from 85

  • Physics - ,

    vf^2=vi^2+2ad

    for a,30*9.8 m/s^2; vf=0, vi= convert to m/s
    solve for d
