You can put this solution on YOUR website!
v=k*sqrt(e)
\n" ); document.write( "120=k*sqrt(1600)
\n" ); document.write( "120=40k
\n" ); document.write( "k=120/40
\n" ); document.write( "k=3
\n" ); document.write( ".
\n" ); document.write( "21=3*7
\n" ); document.write( "e=7^2=49 e joules
\n" ); document.write( ".
