The formula is \"x+=+%281%2F2%29%2Aat%5E2+%2B+v%5B0%5Dt\"
\n" ); document.write( "where \"v%5B0%5D\", initial velocity is zero
\n" ); document.write( "\"50+=+%281%2F2%29%2Aa9%5E2\"
\n" ); document.write( "\"100+=+81a\"
\n" ); document.write( "\"a+=+100%2F81\"
\n" ); document.write( "This is the change in velocity/time from start to finish, so
\n" ); document.write( "\"%28v%5Bf%5D+-+0%29%2F9+=+100%2F81\"
\n" ); document.write( "\"v%5Bf%5D+=+9%2A%28100%2F81%29\"
\n" ); document.write( "\"v%5Bf%5D+=+100%2F9\" m/sec
\n" ); document.write( "
\n" );
