Chapter 5, Problem 2Q

Two horizontal forces,

${\stackrel{\to }{F}}_1=\left(3\text{ N}\right)\hat{i} -\left(4\text{ N}\right)\hat{j}\text{ and }{\stackrel{\to }{F}}_2=-\left(1\text{ N}\right)\hat{i} -\left(2\text{ N}\right)\hat{j}$

pull a banana split across a friction- less lunch counter. Without using a calculator, determine which of the vectors in the free-body diagram of Fig. 5-20 best represent (a) ${\stackrel{\to }{F}}_1$ and (b) ${\stackrel{\to }{F}}_2$. What is the net-force component along (c) the x axis and (d) the y axis? Into which quadrants do (e) the net-force vector and (f) the split’s acceleration vector point?
