An h2 molecule can be formed in a collision that involves three hydrogen atoms. suppose that before such a collision, each of the three atoms has speed 2000 m/s , and they are approaching at 120 ∘ angles so that at any instant, the atoms lie at the corners of an equilateral triangle. find the speeds of the h2 molecule and of the single hydrogen atom that remains after the collision. the binding energy of h2 is δ=7.23×10−19j, and the mass of the hydrogen atom is 1.67×10−27kg.
