Newton's second law:
Newton's second law implies that the net force is equal to the centripetal force.
Normal force acts perpendicular to the surface upwards.
mg cos θ is perpendicular to the surface and pulls the cars downwards
Fc acts perpendicular to the surface and pulls the car downwards (towards the center of the circle).
A 1100 kg car drives at 30 m/s over a circular hill that has a radius of 400 m as shown in (Figure 1). At the point shown in (Figure 1), what is the normal force on the car?
