4. The distance a body falls from rest (neglecting air resistance) varies directly as the square of the time it falls.
\n" ); document.write( "d = kt^2 where
\n" ); document.write( "d = distance after t time
\n" ); document.write( "t = time
\n" ); document.write( "k = constant
\n" ); document.write( " If an object drops 64 feet in 2 seconds,
\n" ); document.write( "Find k
\n" ); document.write( "k*2^2 = 64
\n" ); document.write( "k = 64/4
\n" ); document.write( "k = 16
\n" ); document.write( "the equation now d = 16t^2
\n" ); document.write( " how many seconds will it take an object to reach the sea if it is dropped from a plane 2500 feet above the sea level? (show complete solution thanks!)
\n" ); document.write( "16t^2 = 2500
\n" ); document.write( "t^2 = 2500/16
\n" ); document.write( "t^2 = 156.25
\n" ); document.write( "t = \"sqrt%28156.25%29\"

\n" );
