An accident investigator estimates that a vehicle hit an advertisement column at a speed of 30 mi/h, based on his assessment of damage. Leading up to the accident location, he observes skid marks of 100 ft on the pavement (F = 0.35), 10 ft on the shoulder (F=0.3), and 75 ft on the grass shoulder (F = 0.25); the grades of the pavement, the shoulder and the grass are 2%, 8% and 6% downgrade, respectively. If the post speed of this highway is 60 mi/h, does the initial speed of the driver is one of the accident cause?

An accident investigator estimates that a vehicle hit an advertisement column at a
speed of 30 mi/h, based on his assessment of damage. Leading up to the accident
location, he observes skid marks of 100 ft on the pavement (F = 0.35), 10 ft on the
shoulder (F=0.3), and 75 ft on the grass shoulder (F = 0.25); the grades of the
pavement, the shoulder and the grass are 2%, 8% and 6% downgrade, respectively. If
the post speed of this highway is 60 mi/h, does the initial speed of the driver is one of
the accident cause?
