For the vectors shown in Figure P320 graphically determine t
     For the vectors shown in Figure P3.20, graphically determine the resultant, R = A + > B.   
  
  Solution
A vector have only x direction component 10i + 0j
and B vector have two x and y direction component 15cos30 i+15sin30 j
= 12.99 i + 7.5 j
vector additiion A+B
=(10+12.99)i +7.5j
= 22.99 i+7.5 j
