The bumper on a car is made of flexible plastic so that it will compress on impact and “cushion” the car’s occupants during a collision. Suppose a car of mass m = 1200 kg is traveling slowly through a parking lot at 2.5 m/s when it strikes a brick wall. (a) What is the approximate value of the maximum compression of the bumper? (b) If the bumper can be modeled as a spring, what is approximate value of the spring constant of the bumper?
