To calculate the forces on a parked car on an incline, begin by drawing a free-body diagram to identify all acting forces. For a Toyota Vios with a mass of 1700 kg on a 15° incline, the normal force is calculated as 1700 kg multiplied by 9.81 m/s² times the cosine of 15°, resulting in approximately 16108.7 N. The static frictional force can be determined without the coefficient of friction by recognizing that it balances the component of gravitational force acting down the slope. Additionally, the car's acceleration is zero since it is parked, indicating that the net force acting on it is also zero. Understanding these principles is essential for solving similar physics problems involving forces on inclined planes.
