Chapter 3, Problem 44EAP

I Four forces are exerted on the object shown in FIGURE P3.44. (Forces are measured in newtons, abbreviated N.) The net force on the object is ${\stackrel{\to }{F}}_{net}={\stackrel{\to }{F}}_1+{\stackrel{\to }{F}}_2+{\stackrel{\to }{F}}_3+{\stackrel{\to }{F}}_4$ = 4.0î N. What are (a) ${\stackrel{\to }{F}}_3$ and (b) ${\stackrel{\to }{F}}_4$ ? Give your answers in component form.
