Question

any help greatly appreciated.

High jump records went up about one foot after the "Fosbury flop" jumping method became widely adopted. Can you explain why? It's not just because all the athletes were better.

Why does the initial running speed and jump angle affect the long jump?

In golf, you add up the scores of separate rounds to figure out the winner, in normal "medal" play.

Try figuring out the latest figure skating scoring methods if you want a good example of complicated mathematics determining the winner.
