a. b. C. Using the graphical method, find the resultant of the following two displacements, 2.0m at 40° and 4.0m at 127°, the angles being taken relative to the + x-axes. (6 marks) Calculate the components of a unit vector that lies in the xy-plane and makes equal angles with the positive directions of the x- and y-axes. (4 marks) Compute the scalar and vector products of A and B given that A= 3i - 5j - 4k and B=4i - 7j+ 12k (10 marks) a. b. C.
