These problems share the same set of vectors. You may find it helpful to sketch the vectors out roughly to add them via the graphical methods described in the text as a "common sense check for the analyti- cal calculations you'll do here. If the graphical addition method reveals a vector sum that's in the third quadrant, for instance, your answer ought to have both the xand y component as negative. In this way you can get a rough check on your work before you submit an attempt. Note the vectors are the same ones as in the previous exercise to make it somewhat easier on you (no need to convert these vectors again as long as you got them correct on the previous exercise).
