Hello TSny, thanks for replying, thing is my professor didn't give us a way to relate P and T however I found this formula in wikipedia but I'm not sure if it's correct: (It's valid iff the process is reversible) P1-γ Tγ=const. What do you think? The statement doesn't specify if the process is...

Homework Statement An engine works with an ideal diatomic gas (γ=1.40) according to a thermodynamic cycle consisting in four processes that take the gas successively through the states 1, 2, 3 and 4. The processes 1 -> 2 and 3 -> 4 take place at constant pressure and the two other processes are...

Agree. You're right. Anyways, is this the way to proceed?

OK. That's my bad, I'm sorry. We're in 2 dimensions. v represents the initial velocity of the particle. (The one hitting). u represents the final velocity. α, β represent the angles made with the direction of the particle 1 (The one hitting) - α for the one that was moving previously and β...

A particle with mass m is at rest. A second one, identical to the last one hits the first one. Show that in the case of a perfectly elastic collision (Q=0) the directions of the two particles make a right angle. You can't assume that both final velocities will be equal. Here's what I've got...
