\n" ); document.write( "\n" ); document.write( "Its potential energy  P  (in joules)  is the product\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "                     P = m*g*h\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "where  m  is the mass in kilograms,  g  is the gravity acceleration  9.81 m/s^2,   h is the height \r
\n" ); document.write( "\n" ); document.write( "above the reference level  (1.7  meters in this problem).\r
