\n" ); document.write( "A particle moves along the x axis so that its velocity at time t, t > 0, is given by v(t) = \"%28t+-+2%29%2Ft\". If the particle's position at t = 1 is x = 10, write an equation which describes the position of the particle as a function of t.
\n" ); document.write( " Also, what velocity does the particle approach as t get large?
\n" ); document.write( "

To find the position, integrate the velocity.
\n" ); document.write( "\"v%28t%29=1-2%2Ft\"
\n" ); document.write( "So then,
\n" ); document.write( "\"x%28t%29=int%28%28v%28t%29%29%2Cdt%29\"
\n" ); document.write( "\"x%28t%29=int%28%281-2%2Ft%29%2Cdt%29\"
\n" ); document.write( "\"x%28t%29=t-ln%28t%29%2BC\"
\n" ); document.write( "So when \"t=1\",
\n" ); document.write( "\"1-ln%281%29%2BC=10\"
\n" ); document.write( "\"1%2BC=10\"
\n" ); document.write( "\"C=9\"
\n" ); document.write( "\"highlight%28x%28t%29=t-ln%28t%29%2B9%29\"
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "When \"t-%3Einfinity\",
\n" ); document.write( "\"v%28t%29=1-0\"
\n" ); document.write( "\"v%28t%29=1\"
\n" ); document.write( "
\n" ); document.write( "
\n" );
