Homework Statement
Two particles of the same rest mass m have the same kinetic energy of 2.00*mc^2. They move in opposite directions and collide to form a new particle with mass M.
a) What is the momentum of the new particle?
b) What is its kinetic energy?
c) Find the rest mass M of the new particle in terms of m.
Homework Equations
momentum=sqrt(total e.^2-rest e.^2)/c or p=mv
I don't know if I can use total e.=k.e.+rest e. because it is a strange kinetic energy (2.00*mc^2) and I don't know how the new particle is formed...do you have add the two momenta from the two particles to get the momentum of the newly formed particle? I don't know how to start...Thanks for your help and time
