\n" ); document.write( "a rocket is moving vertically upward at a speed of 245 meters per second
\n" ); document.write( "when its fuel runs out. how much farther will it start to travel upward
\n" ); document.write( "before starting fall back to the ground.
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "Write equation relevant to this problem\r\n" );
document.write( "\r\n" );
document.write( "    h(t) = -10*t^2 + 245t + \"h%5B0%5D\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Here h(t) is the current height, t is the time, counted from the moment, \r\n" );
document.write( "when the fuel stopped running;  \"h%5B0%5D\" is the height, where the fuel stop running.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From this equation, find the time \"t%5Bmax%5D\" for the maximum height\r\n" );
document.write( "\r\n" );
document.write( "    \"t%5Bmax%5D\" = \" \"-b%2F%282a%29+\" \" = \"-245%2F%28%282%2A%28-10%29%29%29\" = \"245%2F20\" = 12.25 seconds.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now \r\n" );
document.write( "\r\n" );
document.write( "    \"how much farther\" = -10*12.25^2 + 245*12.25 = 1500.625 meters.    ANSWER\r\n" );
