A neon atom (m=20.0u) makes a perfectly elastic collision with another atom at rest. After the impact, the neon atom travels away at a 46.1 ∘ angle from its original direction and the unknown atom travels away at a -58.9 ∘ angle. What is the mass (in u) of the unknown atom? [Hint: You can use the law of sines.]
