Which of the following expressions gives a quantity that can be measured in joules (J)? [Assume that all quantities are magnitudes.]

The answer is B. Can someone explain how to solve this one?

Hi,

The answer will be B because work is a form of energy and

work= Force x displacement

Force= mass x (velocity/time)

work= mass x (velocity/time) x displacement [v=d/t]

work = mass x velocity x velocity [p=mv]

work= momentum x velocity
