An object moves along a circular path with a constant speed, |⃗vo|.

Question

(Semi Circle with point A on one side point B on the other. Looks like a 90 degree angle with points A and B on either side of the hypotenuse.)

The average acceleration in going from A to B is
1. zero
2. north
3. south
4. west
5. east
6. none of the others

Answer 1

Anything moving in a circle is accelerating so you can eliminate answer one.

And since it's accelerating (a vector) it has a changing direction and magnitude.

Hope that helps, if you want you can tell me what you got and I'll check it.

Answer 2

south
