The equation for Force is:
\n" ); document.write( "F = ma
\n" ); document.write( "where a = m/s^2
\n" ); document.write( "in this problem:
\n" ); document.write( "[0.38(3.0)^2]/1.55
\n" ); document.write( "(0.38*9)/1.55
\n" ); document.write( "you can finish it from here, the result will be the force needed as measured in Newtons
\n" ); document.write( "
\n" );
