Homework Statement
a proton with kinetic energy 10GeV collides with a proton at rest. 1 proton goes off with an angle of 45 degrees relative to the incoming proton. Find the velocity of both protons after the collison. This is an ellastic collision.
E(initial) = 938 mev
i honestly don't know where to start off but here's my attempts at a answer
Homework Equations
The Attempt at a Solution
E=(MC^2)/(1-(v/c)^2)^1/2
V/c= (1-((mc^2)/(E^2)))^1/2 V= .99632c
V= v1 cos (30) + v2 cos(theta)
v1 sin (30) + v2 sin (theta)
E = E1 + E2
10.938 gev = .938 gev/ (1-(v1/c)^2))^1/2 + .938gev/(1-(v2/c)^2)^1/2
substitute and get the answer v1 is .00458
and v2 is .49780
however these answers don't work when put back into the equations..
