Final answer:
The normal force from the road on the car is 5880 N.
Step-by-step explanation:
To find the normal force exerted by the road on the car, we need to consider the forces acting on the car as it goes over the top of the hill.
At the top of the hill, the only vertical force acting on the car is its weight, which can be calculated using the formula Fweight = m * g, where m is the mass of the car and g is the acceleration due to gravity.
The normal force is equal in magnitude but opposite in direction to the weight of the car, so the normal force would have a magnitude of 600 kg * 9.8 m/s2 = 5880 N.
