Which statement about the car is correct?
The acceleration of the car is zero because its speed is constant.
The frictional force from the track provides a resultant force directed towards the centre of the track.
The momentum of the car remains constant because its mass and speed do not change.
The resultant force on the car acts in the direction of its instantaneous motion.
