You can put this solution on YOUR website!
Here's an example of a problem:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If you throw a rock straight up, the position x in terms of time (t) is given by
\n" ); document.write( " $\"x+=+%281%2F2%29at%5E2+%2B+v%5B0%5Dt+%2B+x%5B0%5D\"$ where a is the acceleration due to gravity (9.8 m/s^2), $\"v%5B0%5D\"$ is the original velocity, and $\"x%5B0%5D\"$ is the original position. How long does it take for the rock to hit the ground? (just use the quadratic formula) \n" ); document.write( "

\n" );
