[#167] Components of vectors The vector A in the (x, y) plane has magnitude A = 3.7 and makes angle 0 = 140° with the x axis, where 0 is measured in the geometric or anticlockwise sense. What are the components of in the x and y directions? Hint: draw a sketch first. Write your answer in the form: x, y. For example: 1.5, 2.0 Use the correct number of sig figs. Warning: If you retake a test, you will not necessarily get the same values of parameters the next time around. So you should calculate values again, rather than use your previous answers.arrow_forward
