Final answer:
The friction force can be determined using the centripetal force required for the car to navigate the curve. The friction force is equal to (mv^2)/r.
Step-by-step explanation:
The friction force can be determined using the centripetal force required for the car to navigate the curve. The centripetal force is given by the equation Fc = (mv^2)/r, where Fc is the centripetal force, m is the mass of the car, v is the velocity, and r is the radius of the curve. Since the friction force is responsible for providing the centripetal force, it can be equated to Fc. Therefore, the friction force is equal to (mv^2)/r.
In this case, the mass of the car is given as 2000 kg. The velocity and radius of the curve are not provided in the question. Therefore, we cannot calculate the exact friction force without these values.
