Demonstrate and solve the following: Solution: The horizontal component is M, = -3 m. Note that it is negative since it is directed to the left.The vertical component, on the other hand, is M, = +5 m. It is positive since it is directed upwards. Solvingfor the magnitude M,M = M? + M3M = (-3)2 + (+5)²M = 5.8310 mSolving for the reference angle 6,e = Arctan|M,e = Arctane = 59.0362°Since the x- and y-components of M are negative and positive, respectively, applying the sign conventionfor Cartesian coordinates, the vector can be located to be facing the second quadrant.Hence, vector M is 5.8310 m, directed 59.0362° with respect to the horizontal, located in quadrant II.Practice Problem: A vector N is known to start at the origin and to end at (5,-4).
