Person A pushes a $2 \text{ kg}$ mass constantly with some force. The mass moves on a rough surface with coefficent of friction $\mu = 0.5$. The mass moves a total of $1 \text{ m}$ at constant velocity of $.2 \text{ m}/\text{s}$ while person A is pushing.

In a second experiment, a ball of mass $.5 \text{ kg}$ falls from a height of $2 \text{ m}$. Person B catches it after falling $2 \text{ m}$, bringing it to rest.

Who does more work in total?
