- Homework Statement
- Three particles A, B, and C, each of mass π, 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 π’.

The masses of A, B, and C are now π, 2π and 3π respectively:

Again find the fraction of π’ 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: πΎ=0.5ππ£^2

Momentum: π=ππ£

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!
