I'm trying to solve a set of three equations describing a pion-proton collision that produces a kaon and a lambda particle. I tried the following code, but Mathematica 9 doesn't seem to want to give me any response whatsoever for the last Solve function. I don't know why; any help would be appreciated.
thanks, Brett

g[v_] := 1/Sqrt[1 - v^2/c^2]

vCM[v_] := g[v] mPI v c^2/(g[v] mPI c^2 + mProt c^2)

uZPI[u_] := mProt u/(mProt + mPI Sqrt[1 - u^2/c^2])

uzProt[u_] := -mPi u/(mPI + mProt Sqrt[1 - u^2/c^2])

In[8]:= FullSimplify[g[uZPI[u]]]
Out[8]:= ...

In[9]:= FullSimplify[g[uzProt[u]]]
Out[9]:= ...

Solve[{ mPI u/Sqrt[1 - u^2/c^2] ==
mK vK/Sqrt[1 - vK^2/c^2] + mL vL/Sqrt[1 - vL^2/c^2],
kPI/c^2 + mPI + mProt ==
mK/Sqrt[1 - vK^2/c^2] + mL/Sqrt[1 - vL^2/c^2],
Out[8] mPI + Out[9] mProt == mK + mL}, {u, vK, vL}]
