None of the Above

The four values of "f" in the table above correspond to the coefficient of friction for four road conditions. Match these values to the appropriate conditions by looking at the braking distance required.

Okay Road with fair tires.

f = 0.30

Icy Road

f = 0.90

Wet Road

f = 0.70

Very Good Road with great tires.

f = 0.50
