You can put this solution on YOUR website!
Given:
\n" ); document.write( " r = 2(5L)^1/2\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "where r = 60
\n" ); document.write( "
\n" ); document.write( " 60 = 2(5L)^1/2
\n" ); document.write( " 30 = (5L)^1/2
\n" ); document.write( "
\n" ); document.write( "Square both sides
\n" ); document.write( " 900 = 5L
\n" ); document.write( " L = 180\r
\n" ); document.write( "\n" ); document.write( "The car will skid 180 ft.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
