Homework Statement
I was doing d and had a question because I believe my response is perfectly acceptable but yet it does not reflect the scoring guidelines at all. By the way I believe this is free response #2 on the 2006 Form B AP Physics B test

Homework Equations
I answered using the coefficient of restitution. I use it all the time when I'm asked for the type of collision

click on link and zoom in once to read what the coefficient of resitution is if you do not know what it is

Here's the scoring guidelines

so my question is how would my response be scored? My response is not wrong at all it is as AP would put it "Alternate Solution" as I often see on scoring guidelines. I do not if AP likes people using e when responding to problems of momentum but it's a perfect valid solution...
so what do you think? how would my response be scored?
