SOLUTION: Approximate speed car traveling when brakes are suddently applied, use equation S=4.47L�. S= speed of car in miles per hour and L = length of skid marks left by the tires in feet.

Question 148505: Approximate speed car traveling when brakes are suddently applied, use equation S=4.47L�. 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?

Approximate speed car traveling when brakes are suddently applied,
use equation S=4.47L�.
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
================
