$1)$ Part l: If I have a system that consists of my hand, a ball, and the Earth, where my hand has lifted a $2$ kg ball from $1$ m high to $3$ m high, how much work has my hand done on the ball?

Part $2$: I have an energy bar chart $($seen right$).1)$ What does this imply about the amount of energy in my system? $2)$ If this represents the scenario of a cable holding up an elevator that is traveling and then stopping, what direction did the elevator move in$?$
