This is the question that i have on my paper... Two discs (both circular shape) on a frictionless table, disc 1 with mass 100g moves with velocity 1m/s and collides "head on" elastically without any energy loss with disc 2 with mass 200g and motionless; what will be the final velocity after...

Hello all, I have a relative simple question, but I'd like to double check with you folks. Typically, in normal atmosphere the kinetic energy of water molecules in water, should be lower than the kinetic energy of water molecule in hot vapor, isn't that right? Thank you! /cheers!
