Homework Statement
We have a particle mass ##m## with kinetic energy ##k## colliding with a stationary particle of mass ##2m##. The collision creates a composite mass of ##\sqrt{17}m##. Find the value of ##k##
Homework Equations
The Attempt at a Solution
I have tried using mass-energy conservation and also momentum conservation, but I can't seem to get the required result of ##k=2mc^2##
