A block lies on a plane raised an angle Theta from the horizontal. Three forces act upon the block. overrightarrow (F)_(w) the force of gravity; overrightarrow (F)_(n) the normal force; and overrightarrow (F)_(f) the force of friction. The coefficient of friction is large enough to prevent the block from sliding (Eigure 1) Previous Answers square Part B Which forces lie along the axes of the coordinate system b, in which the y axis is vertical? 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)_(v) overrightarrow (F)_(n) and overrightarrow (F)_(w) overrightarrow (F)_(f) and overrightarrow (F)_(n) and overrightarrow (F)

To determine which forces lie along the axes of the coordinate system \( b \), where the \( y \)-axis is vertical, we need to consider the orientation of each force relative to the coordinate system.<br /><br />1. **\(\overrightarrow{F}_w\)** (Force of gravity): This force acts vertically downward and is parallel to the \( y \)-axis.<br />2. **\(\overrightarrow{F}_n\)** (Normal force): This force acts perpendicular to the plane of the surface, which means it is also perpendicular to the incline and thus lies along the \( y \)-axis.<br />3. **\(\overrightarrow{F}_f\)** (Force of friction): This force acts parallel to the plane of the surface and opposite to the direction of potential motion, which means it lies along the \( x \)-axis.<br /><br />Given this information, the forces that lie along the axes of the coordinate system \( b \), where the \( y \)-axis is vertical, are:<br /><br />- \(\overrightarrow{F}_n\) (normal force)<br />- \(\overrightarrow{F}_w\) (force of gravity)<br /><br />Therefore, the correct answer is:<br /><br />\(\overrightarrow{F}_n\) and \(\overrightarrow{F}_w\)
