Bump!

Any help?

Not a problem, but I actually got 7.84 m/s2 lol. Anyone else want to check our answers?

Update: I'm guessing that since the cup is on a horizontal table, the degrees of freedom is 9. Therefore the energy must be halved. Q = 39243.75 J Plug it into: KE = (1/2)mv2 v2 = (2KE) / m = (2*39243.75) / .250 = 313950 √v2 = √313950 v = 560 m/s Can anyone confirm that...

The first box: x-forces: T - K = ma T - (0.1)(N) = 2a y-forces: N - w = o N = w N = 2g N = 9.8 The second box: T - w = m2a T - m2g = 1a T - 9.8 = a Solve that.

I can't really follow your formula, but what did you get for acceleration once you solved?

The rope and pulley are most likely massless. The y-component of acceleration for block 1 should be zero. See how that works.

Homework Statement Suppose a cup of boiling water (m=250g) instantaneously cools to room temperature (25°C) with the liberated thermal energy going into translational KE. How fast will the cup fly off the table? Assume the water molecules have 18 degrees of freedom. Homework Equations...

Thanks for your reponse! And wow never thought of that... I thought it was pretty common with physics majors (im a bio major btw). Sorry about that. It's basically a method of being able to capture the movement of fluids (mostly gases). Here's some cool vids that can explain it a lot better than...

Alright no ideas huh lol... how about anything regarding ferrofluids? What kind of research can be done with them? Hope I have better luck with this one lol

Last bump... lol any help? I have to submit everything in within the next week to get everything approved for next semester. Anything is appreciated!

Bump! Any help will be greatly appreciated.

Hey guys, As you can see this is my first post on the forum. I came here hoping to find some ideas for doing research with Schlieren photography. I am currently a senior in university and want to do research in physics for my final semester here. I came across Schlieren photography while...
