The company you work for needs you to design a bumper for a car with a mass of 1500 kg. The impact force must be less than 200 kN at a speed of 50 km/h when the car crashes into a concrete wall. If your design is successful, how long will it take the car to come to a complete stop after the impact?

The drag force, fd, imposed by the surrounding air on a vehicle moving with velocity v is given by fd = cdaρv 2/2 where cd is a constant called the drag coefficient, a is the projected frontal area of the vehicle, and ρ is the air density. an automobile is moving at v = 80 kilometers per hour with cd = 0.28, a = 2.3 m2, and ρ = 1.2 kg/m3.
