A particle of mass m moves in a center of mass frame of reference with a momentum p=2m. The center of mass moves with a speed v along the axis in the frame of reference of the laboratory. What's the angle of the particle in the frame of reference of the laboratory. What i think I have to do...

So I tried this resistance thing. I just took some microphone cable, divided it into two parts and connected them to two coins. I plugged the cable into my microphone port on my laptop and used a voice recording program. When I put the coins into the water the program started recording sound...

Maybe I will be able to do that myself. Got to think about this a little bit. Thanks for your help.

I live in Poland and it is pretty hard to get these kind of things around here, but this would really make the process of data collecting much faster. I have to think about that. I would also have to come up with some smart equation to calculate the height from the resistance.

Man, the lines idea is super cool. I haven't had a slightest idea of that sort, you have to be really good at experiments. Thank you, thank you, thank you!

This is a part of my final High School mark, so I am not going to be too cheap on it. The plexiglass tank, however, seems a bit hard to build. How would you measure the height of the wave in my place (if I used the guttering)?

Hey thanks for a quick response. I don't need to take a photo of the whole thing, I have two cameras and that would be enough. The only problem is how to measure the height of the wave. Is the guttering thin enough for me to take a photo of it's side and see the waves shadow?

(I'm not sure if I posted this topic in the appropriate category. The project I'm discussing is for my school, but seems bigger and different than a homework question. If it's not the right section I'm sorry) I want to measure the relationship between various aspects of wind generated waves...
