2 people are standing on a very light board that is balanced on a fulcrum. The lighter person suddenly jumps straight up at a 1.5 m/s. Just after he jumps, how fast and in which direction will the heavier person be moving?

*Diagram has a guy jumping up which weighs 50 kg and he is 2.4m from the middle of the board. The other guy is just standing on the other side (1.6m from the middle of the board) He weighs 75.*
