Your friend Gina just got a new pool with a diving board. When a person is standing still on the end of the diving board, the vertical distance it bends downward is proportional to the weight of the person standing. It's actually quite hard to stand totally still on the end of the board, and it usually has a small amount of oscillation.

When Gina stands on the end, the board oscillates with a 5% larger frequency than when you stand on the end.

What is the ratio of Gina's mass to your mass?
