At the scene of a car accident, the forensic investigator measured the skid marks from one of the vehicles to be 83 m long. He also knows the typical acceleration for a car when you slam on the brakes is -4 m/s2. The speed limit for this area is 100 km/hr (about 28 m/s). Was the car speeding before it hit the brakes?
