Another darned Physics (or Psycho) question. Any help greatly received.
Hi
The first question can be answered using... the conservation of the linear momentum of the two particles : we know their mass and their velocity, we also know that the mass of the coalesced particle is hence
And this can be solved for and .
For the second question you've to compute the kinetic energy of the three particles since you're asked to evaluate .
This question links nicely with this htread: http://www.mathhelpforum.com/math-he...ors-t-0-a.html
