Please find the solution attached.
• In Newtonian mechanics momentum is always conserved, while total energy is conserved if and only if the all forces (internal and external) in the system are conservative.
• In relativistic mechanics both momentum and total energy are always conserved.
In the stationary (lab) frame we have a particle that moves with velocity
We start with the basic postulate of special relativity that the four-line element is invariant at any system:
The expert states the conservation of momentum and kinetic energy in collision in classical mechanics and relativistic mechanics. The relativistic kinetic energy is derived.
