The centripetal acceleration on an object in uniform circular motion
A. is directed tangent to the circle
B. points away from the center of the circle
C. points toward the center of the circle
C. points toward the center of the circle
Acceleration is in the same direction as ?v. If you place this ?v vector at the
midpoint between v1 and v2 you see that it points towards the center.
