# A block of mass M moves up a rough incline that makes an angle \(\theta\) with the horizontal. A person pushes the block with a constant external force of magnitude F directed horizontally to the right, as shown. Which of the following lists all the forces exerted on the block along with their correct directions?

A block of mass M moves up a rough incline that makes an angle \(\theta\) with the horizontal. A person pushes the block with a constant external force of magnitude F directed horizontally to the right, as shown. Which of the following lists all the forces exerted on the block along with their correct directions?

![A right-triangular wedge represents an incline resting on a flat horizontal surface, sloping upward to the right at an angle labeled \(\theta\). A rectangular block of mass M rests on the inclined surface. A single horizontal arrow labeled F points to the right toward the left side of the block. A small arrow labeled v is drawn above the block parallel to the inclined surface, pointing up and to the right. No other labels, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1787460094-EoAAsl.jpg)

- **A.** Gravitational force directed vertically downward, normal force directed perpendicular to the incline surface and away from it, kinetic friction force directed down the incline parallel to the surface, and applied force directed horizontally to the right.
- **B.** Gravitational force directed vertically downward, normal force directed perpendicular to the incline surface and away from it, kinetic friction force directed up the incline parallel to the surface, and applied force directed horizontally to the right.
- **C.** Gravitational force directed vertically downward, normal force directed vertically upward, kinetic friction force directed down the incline parallel to the surface, and applied force directed up the incline parallel to the surface.
- **D.** Gravitational force directed vertically downward, normal force directed perpendicular to the incline surface and away from it, kinetic friction force directed down the incline parallel to the surface, applied force directed horizontally to the right, and a forward force of motion directed up the incline parallel to the surface.
