questions about the physics of diving?

I need some help with these questions on a piece of physics tutorial. I kind of know the answers, but I'm having a problem with the text and using the right terms. (a) Discuss / Explain why the belly-flops (of a certain height) hurts so much, while not graceful dives. (b) Discuss / explain the relationship between the height of the dive and the rate at which fell into the water. (c) Having made a diving reasonably well, you try again but this time runs faster in the diving platform than before. What difference does this make? (D) For the final dive run at the same speed as before on the platform, but you decide to do two somersaults during the dive. Does this alter the venue and / or when you hit the water?

a) The larger surface area exposed to water, the harder it is to enter the water and offers more resistance than water and it hurts. b) It is a joke right? The more high dive, the faster you enter the water …. ignoring terminal velocity. C) I'll give it a horizontal component in their movement when entering water if running before diving. D) the dish will still dive, regardless of what you do in the air. If he does evil come immersion water wrong and will do harm and A Bigger Splash that if the drive correctly and entered the water properly.
