center of mass velocity greater than 1c?
Basically I have two electrons moving in opposite directions towards each other.
One is moving 2.5x10^8 m/s and the other is 2.0x10^8 m/s and I'm trying to use the
following equation for finding the center of mass velocity:
V_cm = ((p1 + p2)c^2)/(E1 + E2)
I calculated the momentum's and energies to be,
p1 = 456280 eV/c
p2 = 769846 eV/c
E1 = 174216 eV
E2 = 413132 eV
and the V_cm = 2.08756 c?
Is that supposed to happen, shouldn't it be less than 1?
