The front 1.20 m of a 1,250-kg car is designed as a "crumple zone" that collapses to absorb the shock of a collision.(a) If a car traveling 28.0 m/s stops uniformly in 1.20 m, how long does the collision last? _____________________s (b) What is the magnitude of the average force on the car? _____________________N (c) What is the magnitude of the acceleration of the car? Express the acceleration as a multiple of the acceleration of gravity. _____________________g
