Theoretically, if the objects have the same mass and are moving towards each other at a speed of 
, after a perfectly elastic collision, the object A is supposed to move with the same velocity in the opposite direction.

Explanation:
The de broglie wavelength is given by :
Here,
h is Planck's constant
p is momentum
Momentum and De-Broglie wavelength has inverse relationship. If momentum of an electron double, its wavelength gets half.
