Awesome! thank you, I was just regrouping my terms sloppily. Once looking at the 4 momenta it became clear very quickly!

Homework Statement A lambda particle decays into a proton (at rest) and a pion. The rest masses are: lambda: 1116 MeV/c^2 pion: 140 MeV/c^2 proton: 938 MeV/c^2 we want to find the energy of the a) pion b) lambda (before decay) Homework Equations I am assuming we need to use the...

Homework Statement A spaceship moves with a velocity 0.75c xhat with respect to the earth. The ship releases a probe with a velocity 0.75c yhat relative to the ship. What is the velocity of the probe as viewed on earth, magnitude and direction? Homework Equations The velocity-addition...
