Hi, my problem is this: The diagram shows a crate with mass m=36.3kgm=36.3kg being pushed up an incline that makes an angle ϕ=20.7∘ϕ=20.7∘ with the horizontal. The pushing force is horizontal, with magnitude P, and the coefficient of kinetic friction between the crate and the incline is μ=0.31μ=0.31. Consider the work done on the crate as it moves a distance d=5.28md=5.28m at constant speed. How do I find the work done by gravity? And the net work done by the pushing force, friction, and gravity?

Transcribed Image Text:The image depicts a rectangular block on an inclined plane.
**Description:**
- **Inclined Plane:** The surface is at an angle and represents an inclined plane, sloping upwards from left to right.
- **Angle (φ):** This is the angle between the base of the plane and the inclined surface, denoted by the Greek letter phi (φ).
- **Block:** The rectangular block is resting on the inclined plane.
- **Blue Arrow (P):** A blue arrow, labeled "P," points horizontally towards the block, indicating the direction and perhaps the magnitude of an applied force acting on the block.
This diagram is typically used in physics to illustrate the effects of forces acting on objects on an inclined plane, allowing the analysis of components such as gravitational force, normal force, and frictional forces.
