2. A police officer used the model d 0.1v2 +1.1v for a car's stopping distance, where v is the car's speed in miles per hour. Is there overspeeding if a driver leaves 5 car lengths, approximately 75 fect, between him and the driver in front of him? What is the maximum speed he can drive and still stop safely?
