### Physics Problem

**Q7.** You push a 100-kg file cabinet up on a ramp with a force of 500 N; your push force is parallel to the ramp. The cabinet moves a distance of 8.0 m. The coefficient of kinetic friction is 0.30. During this process,
*Clearly show all work!*

**a) What is the work done by the push force?**

**b) What is the work done by the normal force?**

**c) What is the work done by the weight force?**

**d) What is the work done by the friction force?**

**e) What is the net work? What is the final speed of the file cabinet?**

#### Diagram Description
The diagram shows a 100-kg file cabinet being pushed up a ramp inclined at an angle of 10 degrees. A person is pushing the cabinet upward along the incline. The ramp is situated on a flat green surface, and the angle of inclination is labeled as 10 degrees.

### Explanation of Relevant Concepts

- **Force (N):** Newton's measure of force.
- **Work (J):** Work is the measure of energy transfer when an object is moved over a distance by an external force.
\[
\text{Work} = \text{Force} \times \text{Distance} \times \cos(\theta)
\]
- **Kinetic Friction:** Frictional force opposing the motion of objects sliding over a surface.
\[
\text{Friction Force, } F_f = \mu \times N
\]
Where \(\mu\) is the coefficient of kinetic friction and \(N\) is the normal force.
- **Normal Force (N):** Perpendicular force exerted by a surface to support the weight of an object resting on it.
- **Gravitational Force \(F_g\):** \(F_g = mg\), where \(m\) is mass and \(g\) is gravitational acceleration (\(9.8 \, m/s^2\)).

### Calculations

For part **a)**, **b)**, **c)**, and **d)**, we'll need to calculate the normal force, gravitational force components, friction force, and then apply these to work equations.

For part **e)**, we'll sum the individual works to find the net work and use the work-energy

Explorers in the jungle find an ancient monument in the shape of a large isosceles triangle as shown in Figure P9.25. The monument is made from tens of thousands of small stone blocks of density 3 800 kg/m3. The monument is 15.7 m high and 64.8 m wide at its base and is everywhere 3.60 m thick from front to back. Before the monument was built many years ago, all the stone blocks lay on the ground. How much work did laborers do on the blocks to put them in position while building the entire monument? Note: The gravitational potential energy of an objectEarth system is given by Ug = MgyCM, where M is the total mass of the object and yCM is the elevation of its center of mass above the chosen reference level.
