I was thinking of a point particle with infinitesimal mass like that but I don't think that's what the problem is about. Thank you! I'll be back no doubt!

Yes I did find it algebraically, but there is something wrong because then the mass would just be zero which can't be true.

I'm guessing zero so I should probably put both

Sweet haha thanks you guys so much!

Is it just 1?

My attempt:

When I change it to momentum I think it just solves for the equation we already have right? By the way thank you so much for helping! I'm sorry I'm so bad at this :/

Okay so is this correct? Can you square both sides of that equation? Here is my attempt and now I'm stuck...

How does finding that vector help me solve for n?

The momentum should be equal since it is elastic so I'm assuming the vector before the collision should be equal to the vectors after the collision right? So I solved for two different equations. Separated them by x and y components. I'm not sure what to solve for now. I really need help I have...

Here is also my response using momentum instead of kinetic energy, but the professor said to use kinetic energy. http://i934.photobucket.com/albums/ad181/Blake1090/d0e18bfb-e695-42e9-9f3e-45511a029a08_zps8953c0a9.jpg

1. Two masses, m and M are involved in a glacing collision as seen below where θ and ø= pi/2. If M = nm what must n be such that the collision is elastic? Remember if θ+ø=pi/2 then cos(θ)=sin(ø) and cos(ø)=sin(θ)...
