completes one full trip around the track. Which of the following can explain why the car gains
Energy stored in the fuel is converted to mechanical energy.
A component of the frictional force exerted by the ground on the tires is directed toward
the center of the circle.
A component of the frictional force exerted by the ground on the tires is in the direction of
The car’s velocity and acceleration are perpendicular.
