Homework Statement
.An atom at rest can undergo radioactive decay, ejecting an electron at a maximum speed of 0.5c. If the atom in a particle accelerator is observed to produce an electron traveling at 0.75c, at least how
fast must the atom itself have been moving?
Homework Equations
u0 x =(ux −v )/(1−uxv/c^2)
The Attempt at a Solution
The problem is asking for the speed of the atom,
I set
ux=0.5c
v=0.75
After plugin in, I get the result of -0.4c
I don't feel sure aboout this anwser.
Any suggeestions? Corrections?
