There is a pulley system, identical to system (ii) in the following image:

A 1.24 kg canister hangs from one pulley, you are lifting with constant speed, what is the work you do while lifting the canister 1.60 cm and a force 6.08 N?

2. Relevant equations

W = F x D (displacement) x Cos theta (where theta is the angle between work and displacement

3. The attempt at a solution

I originally just plugged in my values into the formula and yielded -0.09728 J. When I got it wrong I did a little looking around and tried both multiplying and dividing by 2. Here are all my attempts: 0.0486 J, -0.0486 J, -0.09728 J, 0 J, 0.09728 J, 379.75 J, 0.218 J, -0.218 J
