Given information
Given:
The mass of the neon atom is .
Initial velocity of another atom=
After the collision, the neon atom moves at an angle of and the unknown atom moves at an angle down the x-axis.
Step-by-step explanation
Step 1.
Let the mass of the unknown atom be .
final speed of another atom=
Let the final speed of the neon atom be .
since its the case of elastic collision, momentum and energy of the system will be conserved
using the law of sines,
which gives,
