An atom of mass m₁ = m moves in the positive x direc- tion with speed v₁ = v. It collides with and sticks to an atom of mass m₂ = 2m moving in the positive y direction with speed v₂ = 2v/3. Find the resultant speed and direc- tion of motion of the combination, and find the kinetic energy lost in this inelastic collision.
