A person who is properly restrained by an over-the-shoulder seatbelt has a good chance of surviving a car collision if the deceleration does not exceed 30 "g's"(1.00g = 9.80 m/s2). 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 110 km/h.
