# Flies Flying in Circles

SATPHY-EYFKTQ

The small oval speck pictured directly below represents a fly moving around in the air in a circular path at a constant speed. The radius of the circular path is $r$, as seen in the picture.

If each of the diagrams among the possible answers shows flies with the same acceleration as the one pictured directly below, which fly has a speed that is twice the speed of the fly pictured directly below?

A
B
C
D
E

None of the objects in this question are accelerating, since they all are moving at a constant speed.
