Ok, I see now. I didn't think to look at it that way. I see they boil down to the same ratio and understand why the ratio between the kinetic energies is the most important part. Thank you all!

Yes, I see what you mean and I see that ##\frac{K_{A}}{K_{B}} = \frac{m_{B}}{m_{A}}## and this allows me to solve for the velocity of A but this is just using the conservation of energy and doesn't seem any different from what I had done before. I guess what I don't understand is why when I find...

I was working on this problem but after getting to the answer I questioned the methods that I used for previous problems that I had solved. I understand that the total energy of the system remains constant and that we use the conservation of momentum to relate the two velocities. This gives two...

Thank you both for these responses as its cleared up my confusion for this problem. I guess I need to move away from thinking of these problems as purely a math exercise and consider the physical constraints. I now see why 2 carbons with 20 hydrogrens isn't a real answer and 3 and 8 is the only...

Hello, I am having some trouble finishing this problem from my textbook and would like some insight on the problem. We are looking for the molecular formula of a hydrocarbon. So, if we let x = number of C atoms and y = number of H atoms then we need to find ##C_xH_y##. From the problem...

Hello! My name is Zachary and I am currently in the process of self-studying Physics and Chemistry. I went to school for Computer Science and since graduation, I've found that I've needed somewhere to ask questions and be in a community of people interested in the same subjects. Unfortunately, I...
