Question

A car (m =  1700 kg) is parked on a road that rises  19° above the horizontal. What are the magnitudes of (a) the normal force and (b) the static frictional force that the ground exerts on the tires?

In this diagram, a car is depicted on a sloped incline, illustrating the concept of forces acting on an object on an inclined plane. The key elements in the diagram are:

1. **Car on an Incline**: The car is positioned on a slope, demonstrating how objects interact on inclined surfaces.

2. **Force Vectors**: Two primary force vectors are shown:
   - **\( \vec{f}_s \)** (Static Friction Force): This vector points up the incline, indicating the force of static friction. It prevents the car from sliding down the slope.
   - **\( \vec{F}_N \)** (Normal Force): This vector is perpendicular to the surface of the incline. The normal force represents the perpendicular contact force exerted by a surface on an object in contact with it.

3. **Incline Angle (\( \theta \))**: The angle \( \theta \) is depicted between the horizontal surface and the incline. This angle is crucial for calculating the components of the forces acting on the car, such as gravitational force along and perpendicular to the incline.

This visual aid effectively demonstrates the dynamics of objects on inclined planes, emphasizing static friction and normal force's roles in equilibrium.
