A motorist suddenly notices a stalled car ahead and slams on brakes with an acceleration of 6.3 m/s^2. Unfortunately, the car collides. Police estimate the first car was moving at 5.0 m/s at the moment of the collison. They also measure skid marks 34 meters long. Assume each car has a mass of 1500kg. The speed limit on the road was 45 miles per hour. Was the incoming car speeding (i.e before applying the brakes)?
