\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~\r

\n" ); document.write( "\n" ); document.write( "The presented formulation has a number / a lot of deficiencies. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "

\r\n" );
document.write( "1.  The formulation does not say that the motion is uniformly accelerated.\r\n" );
document.write( "\r\n" );
document.write( "    (Otherwise the problem doesn't make sense).  So, this assumption MUST be added.  \r\n" );
document.write( "\r\n" );
document.write( "     And if it is so, then the initial velocity is zero and the acceleration is a = 10 m/s^2.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "2.  What are these \"next 4 seconds\" ?? - Are they 3-rd, 4-th, 5-th an 6-th seconds (if to understand it literally as it is written) ??\r\n" );
document.write( "\r\n" );
document.write( "    \r\n" );
document.write( "    Then it is consistent with a = 10 m/s^2, but then this part is unnecessary, excessive and carries ZERO additional information.\r\n" );
document.write( "

\n" ); document.write( "\n" ); document.write( "After saying all of that, I have no any desire to work on it further.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The problem MUST BE RE-EDITED to be considered.\r
\n" ); document.write( "

\n" ); document.write( "\n" ); document.write( "-----------
\n" ); document.write( "The solution is based on the formula S = $\"%28at%5E2%29%2F2\"$ .
