Problem 45P

(III) A neon atom (m =20.0 u) makes a perfectly elastic collision with another atom at rest. After the impact, the neon atom travels away at a 55.6° angle from its original direction and the unknown atom travels away at a -50.0° angle. What is the mass (in u) of the unknown atom? [Hint You could use the law of sines.)

Step-by-Step Solution:

Solution 45P:

We have to determine the mass of the unknown atom on which the neon atom is colliding, such that the collision is perfectly elastic collision.

Step 1 of 6

Concept:

Perfectly elastic collision: In a perfect elastic collision, the momentum of the system and as well as the total energy of the system remains conserved.

Law of conservation of linear momentum: According to law of conservation of linear momentum, the total momentum of the system before collision is equal to the total momentum of the system after the collision.

Law of conservation of energy: According to law of conservation of energy, the total energy of the system before collision is equal to the total energy of the system after collision.
