### Understanding Forces in a Playground Scenario

**Problem 3:**

At the playground, you pull an 18-kg sled across the floor with a strap inclined at an angle of θ = 60° above the horizontal. You also push on the sled with a force P = 10N. The sled moves at a constant speed and the coefficient of kinetic friction (μₖ) between the sled and the floor is 0.38. Consider the following:

1. **(a) Find the Normal Force.**
2. **(b) Find the Tension in the strap.**
3. **(c) What happens as the angle θ approaches zero? Is it easier or harder to pull the sled? Show and Explain.**
4. **(d) Now suppose the speed is not constant. What is the acceleration of the sled in terms of F, θ, μₖ, and m?**

**Sketch and Label all the forces:**

Define the coordinate axis for each mass.

**Diagram Description:**

The image shows a person pulling a sled with a strap. The forces are indicated as follows:
- **P**: A horizontal force acting on the sled, representing the push on the sled.
- **F**: The force in the direction of the strap, inclined at an angle θ = 60°.
- A coordinate system should be defined where horizontal and vertical force components can be analyzed.

This exercise involves analyzing the forces acting on an object and requires applying concepts of physics such as normal force, tension, friction, and acceleration.
