Physics EE topics - good or bad?

OK, I'm really late with my EE but I have some ideas, I just need to know if they are any good, so I decided to ask you guys.

The first idea would be to measure the velocity of something using the doppler effect, I would have acces to the equipment but is it too simple?
The second idea is to find absolute zero like they do here:

And the third idea would be to study the motion of a tennis(mby golf) ball. But I don't know how to get hold of any equipment or how to really study it.

Thank you in advance! :tsr2:

The thing is that I have really tried to think of an topic like that but I can't do it...and the doppler thing would be easy to do and I already have everything I need for it. But I also want a good grade! :s-smilie:

My physics teacher said that it was mby a bit narrow but that it could work, and I don't think they would be really happy if I changed it...
WHY DOES THIS HAVE TO BE SO HARD? :O :O :O
