A rock falls from a tower that is 132.3 m high. As it is falling, its height is given by the formula
\n" ); document.write( "h = 132.3 - 4.9t2. How many seconds will it take for the rock to hit the ground (h = 0)?
\n" ); document.write( "--------------
\n" ); document.write( "h = 132.3 - 4.9t2
\n" ); document.write( "h = 0
\n" ); document.write( "132.3 - 4.9t2 = 0
\n" ); document.write( "solve for t
\n" ); document.write( "
\n" ); document.write( "
\n" );
