   A=149.3 @0; B=138.6@120; C=100@216.9
2. Little in way of part scores in each part of question
     a.)2 marks  magnitude of avector does not include 
                 its direction. answer was 2200 at 20 ft.
     b.)4 marks	 Max M occurs where V= 0, x= 11.2
     c.)4 marks  V=2800-250x, x must be measured from A 
3. AB=9810(T); AC=8496(C); BC=6220(C); CD=7617(C)
