Part A

As shown, a force vector F with a magnitude of c $=75\mathrm{.}0$ N is applied at point A and is directed toward point C$.($Figure $1)$ The distance a is $0\mathrm{.}950$ m and the distance b is $1\mathrm{.}55$ m $.$ What are the i$,$ j$,$ and k components of F$?$

Part B

As shown, the cable OA exerts a force on point O of F$=$Fxi$+$Fyj$+$Fzk$.($Figure $2)$ If the cable's length is a$,$ what are the x$,$ y$,$ and z coordinates of A in terms of a$,$ Fx$,$ Fy$,$ and Fz$?$

Express your answers in terms of a$,$ Fx$,$ Fy$,$ and Fz separated by commas.
