A force vector of A has a positive x component of magnitude 5.0 units and a negative y component of magnitude 8.0 units. a) Calculate the magnitude and direction of vector A.
b) When another force vector B is added to vector A it gives a resultant vector of magnitude 2.0 units in the positive x direction. Find vector B.
