527 $ 251-02 GCA_CHO3_Vectors_1 Name: 4). If vector R is as shown in the figure at right and each square of Ty the grid is Im x Im, calculate the magnitude of R. (Show your work). x RA 5). If an angle measured counter clockwise with respect to a reference direction is taken to be positive (+ve), what is the direction of R, with reference to: (Show your work) Positive x-axis: Positive y-axis: Negatice x-axis: Negative y-axis: 5). If vectors A, B, C, and D are as shown in the figure at right and each square of the grid is Im x Im, calculate the magnitudes and directions (in reference to the +ve x-axis) of these vectors. Use trig identities B D to calculate directions. Use the sign convention mentioned in problem #4 for directions. Show your work. x A : Magnitued = Direction = B : Magnitued = Direction = C: Magnitued = Direction = D :: Magnitued = Direction = Mara
