The front 1.20 m of a car of 1,350 kg is designed as a ‘crumple zone’ which collapses to absorb the shock of the collision.
(i) When a car traveling 27.0 m/s stops evenly in 1.20 m, determine how long does the collision last?
(ii) Determine the magnitude of the average force on the car?
(iii) Determine the magnitude of the acceleration of the car? Deduce the acceleration as a multiple of the acceleration of gravity.
