A car created 68.5 m long skid marks at a traffic wreck scene. A State Patrol investigator uses a drag sled to determine that the coefficient of kinetic friction between the road and tire rubber is 0.86. The minimum speed of the car when its driver applied the brakes was (enter your answer with two significant figures) Foet = ma = HN W = mg 2=v + 2aAx m/s
