Approximate speed car traveling when brakes are suddently applied,
use equation S=4.47L½.
S= speed of car in miles per hour and
L = length of skid marks left by the tires in feet.
If 196-foot long skid marks were left by the car, at what speed was it traveling when the breaks were applied?
================
Let L = 196 and solve for S
----------
S = 4.47sqrt(196) = 62.58 mph
================
