**1. Homework Statement**

A 14.0kg bucket is lowered vertically by a rope in which there is 163N of tension at a given instant. What is the acceleration of the bucket.

**2. Homework Equations**

ƩF = ma

_{y}

**3. The Attempt at a Solution**

I know how to solve this but I got it wrong because of the signs.

Since the bucket was being lowered I thought that downward was going to be positive, but the correct solution says that up is positive; WHY?
