An accident investigator estimates that a vehicle hit a bridge abutment at a speed of 22 miles/hour based on his assessment of the damage. Leading to the accident location he observed skid marks of 100 feet on the pavement (F = 0.35) and 85 feet on the grass shoulder (F = 0.245). There is no grade. Estimate the speed of the vehicle at the beginning of the skid marks.
