Three vectors are shown in the figure below, along with an x-y coordinate system. y (m) 34 2- A -5 -4 -3-2 -1 x (m) 5 2 4 --4 Define the vector R to be the vector sum of the following three vectors: 5A, 7B, and -3C. In equation form, R = 5A + 7B - 3C. (a) Find the magnitude of the vector R. m (b) Find the direction of the vector R. Specify the direction as an angle measured counterclockwise from the positive x-axis.
