A person lifts a mass of 20.0 kg vertically upwards at a constant speed of 0.200 m/s through a distance of 0.800 m. What is the work done by the person?
16.0 J
156 J
3.20 J
None of the other choices is correct.

I know that W=M*A*D (Work equals mass times acceleration times distance) and isnt the acceleration 0 here since it is a constant speed? So the answer is D right?
