The homework is online, I just know if I get it wrong. Okay thanks for the help. I'm fairly sure I just screwed up my algebra somewhere, I get n=-1, which is wrong. I solved (1) for W, then plugged that into the conservation of energy. My algebra just isn't as hot as it used to be.

Homework Statement Homework Equations conservation of momentum, m1v1i+m2v2i=m1v1f+m2v2f and conservation of KE, ½m1v1i^2+½m2v2i^2=½m1v1f^2+½m2v2f^2 The Attempt at a Solution first, i defined my variables. v1i=-v2i, v1f=-0.750v1i, v1f=0.750v2i I tried isolating V2f using...
