A ball is dropped from a height of 150ft how long will it take for it to reach the ground?
\n" ); document.write( "objects fall at a rate 32.2ft per second per second (32.2ft squared)
\n" ); document.write( ":
\n" ); document.write( "The average rate of fall from a dropped object: \"1%2F2\"*32.2 = 16.1 ft/sec
\n" ); document.write( ":
\n" ); document.write( "h = -16.1t^2 + 150
\n" ); document.write( "where
\n" ); document.write( "h = height of a dropped object after t seconds
\n" ); document.write( "h=0 when it hits the ground
\n" ); document.write( "-16.1t^2 + 150 = 0
\n" ); document.write( "-16.1t^2 = -150
\n" ); document.write( "Divide both sides by -16.1
\n" ); document.write( "t^2 = +9.31677
\n" ); document.write( "t = \"sqrt%289.31677%29\"
\n" ); document.write( "t = 3.05 sec \n" ); document.write( "
\n" );
