**1. Homework Statement**

A 115kg mail bag hangs by a vertical rope 3.3m long. A postal worker then displaces the bag to a position 2.2m sideways from its original position, always keeping the rope taut.

As the bag is moved to this position, how much work is done by the rope?

**2. Homework Equations**

W=F*d

**3. The Attempt at a Solution**

Tx=-Tcos(theta)

Ty=Tsin(theta)

W=-Tcos(theta)*d

T/3.3m =mg/2.5m to get T

I wanted to know why this is zero. Doesn't the Tension have a negative component in the opposite direction of motion, so the work done will be negative. The answer is zero but I just wanted an explanation on this one. Thanks!
