A ball is tied to a string and swung so that the ball follows a horizontal circular path.

but I also think velocity is constant as the ball should be moving at the same speed and in the same direction; therefore I think it should be option E.-Gravity does not play a part in the acceleration, as the ball is not in free fall.The ball is moving in a circular path, i.e.......
Problem 4: A ball is tied to a string and swung so that the ball follows a horizontal circular path. In this case which of the following statements is true?

A.) The ball has changing velocity and constant acceleration.
B.) The ball has changing velocity and changing acceleration.
C.) The ball has constant velocity and changing acceleration.
D.) None of these.
E.) The ball has constant velocity and constant acceleration.

I tried A thinking that acceleration had to be constant due to gravity, and velocity had to be changing but it was incorrect. After rethinking this problem I still believe acceleration is constant, but I also think velocity is constant as the ball should be moving at the same speed and in the same direction; therefore I think it should be option E.

Gravity does not play a part in the acceleration, as the ball is not in free fall.

The ball is moving in a circular path, i.e. always changing direction, so the velocity is changing.

The acceleration will be changing as well, so the answer is B.

-
I don't know for certain, but since the ball will eventually stop moving, I believe that both the acceleration and the velocity are changing. "B"

-
B. For sure.

-
I am drunk probably now but B.)
It cant be E. if it swung manually.
