Car A: $\"V%5BA%5D\"$ =( $\"70cos%2880%29\"$ , $\"70sin%2880%29\"$ )=( $\"12.2\"$ , $\"68.9\"$ )
\n" ); document.write( "Car B: $\"V%5BB%5D\"$ =( $\"50cos%28120%29\"$ , $\"50sin%28120%29\"$ )=( $\"-25\"$ , $\"43.3\"$ )
\n" ); document.write( "So Car A relative to Car B,
\n" ); document.write( "( $\"12.2-%28-25%29\"$ , $\"68.9-43.3\"$ )=( $\"37.2\"$ , $\"25.6\"$ )
\n" ); document.write( " \n" ); document.write( "
