a sandbag falls out of a hot air balloon that is 144ft above the ground. How long does it take for the sandbag to reach the ground?
\n" ); document.write( "to find the answer, use the equation 0=-16t^2+144 in which the time(t), in seconds, is the time it takes to hit the ground.
\n" ); document.write( "---------------
\n" ); document.write( "use the equation 0=-16t^2+144
\n" ); document.write( "16t^2 = 144
\n" ); document.write( "t^2 = 9
\n" ); document.write( "t = 3 seconds (ignore the t = -3)
\n" ); document.write( "
\n" ); document.write( "
\n" );
