thanks for putting together one cool, informative, helpful site!
on the page
<https://www.euclideanspace.com/physics/dynamics/collision/twod/index.htm> for
the equation:
2 * ((MaMb)/(Ma+Mb) * ((VbiVai) dot n) * n
what is (VbiVai)? It cant be a dot product. You cant just multiply
two vectors afaik. Should this be (Vbi - Vai) ??
and ditto for the next equation also.
thanks, and keep up the good work!

Matthew,
I think you are right, I have corrected the web page. Thank you very much
for pointing this out (and also for your kind comments about the site).
Martin
