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