Jacqueline Casey · Answer 1

a. Normal force

b. Radial force

d. Static frictional force

f. Gravitational force

Explanation:

Static frictional force is opposite to the car's motion, keeping the car from slipping, since it is the only horizontal force acting on the car, the friction force supplies the radial force which causes the uniform circular motion. Vertically, The gravitational force and its respective normal force acts on the car.
