Problem: 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?

FREE Expert Solution

Newton's second law:

F=ma

Centripetal force:

FC=mv2r

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).
