Question

A car race is taking place on the track shown. All the cars are moving at constant speeds. The cars are on curved segments of the track, except for the car at point F. The car at point A has velocity vA, the car at B, vB, etc. Select all the statements that are true, e.g., ABC. If none are correct, enter N.

A )The track is equally curved at point A and point E. If the car at point A has half the speed of the car at point E, its acceleration is the same as that of the car at point E.

B) The acceleration of the car at point A is 0.

C) The acceleration of the car at point D is perpendicular to vD and directed toward the inside of the track.

D) The acceleration of the car at point C is perpendicular to vC and directed toward the inside of the track.

E) If all cars have equal speeds, the acceleration of car B is largest.

F) The acceleration of the car at point B is 0.
