Take a derivative.
\n" ); document.write( " $\"v+=+ds%2Fdt+=+-32t+%2B+160\"$
\n" ); document.write( "At the top point the speed is 0.
\n" ); document.write( " $\"-32t+%2B+160+=+0\"$
\n" ); document.write( " $\"t+=+5\"$
\n" ); document.write( "Evaluate the original function
\n" ); document.write( " $\"s%285%29+=+400\"$
\n" ); document.write( "Done! \n" ); document.write( "

\n" );
