A ball on a frictionless plane is swung around in a circle at constant speed. The acceleration points in the same direction as the velocity vector.

a. True
b. False

I believe it is False, only because the plane is Frictionless. Hope this helps, good luck.

Answer:

False

Explanation:

You have a circle so think back to circular motion. Theres 2 directions, centripetal and tangential. The problem tells you there's a constant tangential speed so tangential acceleration is 0. However there is a centripetal acceleration acting on the ball that holds it in its circular motion (i.e. tension, or gravity). Since centripetal is perpendicular to the tangential direction, acceleration and velocity are in different directions.
