$\"D=4.9t%5E2\"$ , given formula where,
\n" ); document.write( " $\"D=356m\"$ , then,
\n" ); document.write( " $\"356m=4.9t%5E2\"$ ---> $\"cross%28356%2972.65306122m%2Fcross%284.9%29=cross%284.9%29t%5E2%2Fcross%284.9%29\"$
\n" ); document.write( " $\"t%5E2=72.65306122\"$
\n" ); document.write( " $\"t=sqrt%2872.65306122%29\"$
\n" ); document.write( " $\"t=8.52seconds\"$ , round -off
\n" ); document.write( "Thank you,
\n" ); document.write( "Jojo \n" ); document.write( "
