Homework Statement
In frame S , particle 1 is at rest and particle 2 is moving to the right with velocity v.
Consider frame S ′ , moving relative to S , with speed u. Find the value of u such that
the two particles appear in S ′ to be approaching each other with equal but opposite
velocities.
I don't see here how you can get the particles to approach each other.
Homework Statement
Calculate the range of speeds for a particle of mass m in which the classical relation
for kinetic energy is within 1% of the correct relativistic value.
For this can I use K/T = 0.01 and solve for the velocity of the mass, where K is Newtonian KE and T is relativistic KE?
