Consider coordinate system a , with the x axis along the plane. Which forces lie along the axes? overrightarrow (F)_(f) only overrightarrow (F)_(n) only overrightarrow (F)_(W) only overrightarrow (F)_(f) and overrightarrow (F)_(n) overrightarrow (F)_(f) and overrightarrow (F)_(W) overrightarrow (F)_(n) and overrightarrow (F)_(W) overrightarrow (F)_(f) and overrightarrow (F)_(n) and overrightarrow (F)_(W)

The correct answer is: $\overrightarrow {F}_{f}$ and $\overrightarrow {F}_{n}$ and $\overrightarrow {F}_{W}$<br /><br />Explanation: In the given coordinate system, the forces that lie along the axes are the friction force ($\overrightarrow {F}_{f}$), the normal force ($\overrightarrow {F}_{n}$), and the weight force ($\overrightarrow {F}_{W}$). These forces are responsible for the motion and interaction of objects in the coordinate system.
