Homework Statement
In perfectly elastic collision between two atoms, it is always true to say that
a. the initial speed of one atom will be the same as the final speed of the other atom
b. the relative speed of approach between two atoms equals their relative speed of separation
c. the total momentum must be conserved, but a small amount of the total kinetic energy lost
d. whatever their initial state of motion, neither atom can be stationary after the collision
e. none of the above
Homework Equations
conservation of momentum
coefficient of restitution
The Attempt at a Solution
I think the answer is B. Or maybe it is E because it should be relative velocity instead of relative speed?
Thanks
