- Homework Statement
- Three particles A, B, and C, each of mass ๐, lie at rest in that order in a straight line on a smooth horizontal table. The particle A is then projected directly towards B with speed ๐ข.
The masses of A, B, and C are now ๐, 2๐ and 3๐ respectively:
Again find the fraction of ๐ข that C moves with immediately after the second impact, assuming the collisions are perfectly elastic. Give your answer as a decimal to three significant figures.
- Relevant Equations
- Kinetic energy: ๐พ=0.5๐๐ฃ^2
Momentum: ๐=๐๐ฃ

Homework Equations: Kinetic energy: ๐พ=0.5๐๐ฃ^2
Momentum: ๐=๐๐ฃ
Increase in mass = increase in momentum, but not sure if that means an increase in momentum transferred.

I know this may be too easy for advanced physics, but I need urgent help! Thank you!
