title: "There are multiple forces acting on a roller coaster moving around a circular loop on a frictionless track. You know the mass of the roller coaster when fully loaded with passengers. Which of the following identifies all the necessary forces acting on the system in order to make a free-body diagram and calculate the acceleration at the bottom of a roller coaster moving in a vertical circle?"

There are multiple forces acting on a roller coaster moving around a circular loop on a frictionless track. You know the mass of the roller coaster when fully loaded with passengers. Which of the following identifies all the necessary forces acting on the system in order to make a free-body diagram and calculate the acceleration at the bottom of a roller coaster moving in a vertical circle?

- **A.** The gravitational force and the centripetal force.
- **B.** The normal force and the velocity.
- **C.** The gravitational force and the normal force.
- **D.** The centripetal force and the momentum.
