SUMMARY
The normal force acting on a mass of 5 kg on a 30-degree inclined plane can be calculated using the equation Fn = mgcos(θ), where θ is the angle of the incline. In this case, the normal force is Fn = 5 kg * 9.81 m/s² * cos(30°), resulting in approximately 42.44 N. Understanding the relationship between the angle of the incline and the normal force is crucial for solving problems involving inclined planes. Visualizing the forces and drawing a force diagram can significantly aid in grasping these concepts.
