1. The problem statement, all variables and given/known data An object moves along a circular path with a constant speed, |v|. The average acceleration in going from A to B is 1. south 2. zero 3. west 4. north 5. east 6. none of the others 2. Relevant equations a = Δv / Δt tangential acceleration = mv^2 / r 3. The attempt at a solution I'm not sure how to approach this question, but I think that the answer is east. A and B are perpendicular, and at the 45 degree line, the velocity would be pointing due east, so wouldn't the acceleration also? Could someone point me in the starting direction/tell me what I'm missing?
