Hi
This seems like a helpful community so I thought I could ask you guys for some help.
First of all I need to clarify that English is not my first language so you'll have to excuse me if I make any grammatical or spelling errors.
Ok, here's my question:
I'm am trying to calculate the kinetic energy of a person who is standing on a diving board 8 meters above the surface. He weighs 80kgs.
What is his kinetic energy after falling 2m ?
I think it's 1/2*80*9,8^2 = 3841,6 joule
But the textbook tells me I have the wrong answer
I also have to find out his velocity as he reaches the surface, and I have no clue where to even begin.
Any help would be appreciated, thank you.
