## anonymous one year ago Could you explain to me the significance of vf'=[(m1-2m)/(m1+M2)]vi

@arindameducationusc

2. anonymous

I am aware that this equations concerns with a collision between two objects.

3. anonymous

Whether this equation concerns with linear collision or two dimensional collision I don't know.

4. arindameducationusc

yes?

5. arindameducationusc

can you please explain the terms? what are they?

6. arindameducationusc

ok ok wait....

7. anonymous

Sorry I was in the washroom

8. anonymous

Alright so this concerns with conservation of momentum.

9. anonymous

I am unsure as to what v' flick means

10. arindameducationusc

hey,,,, its one dimention..... As component is not there... I haven't revised that, but just went through my notes roughly

11. arindameducationusc

Its a good thing you reminded me, Once I revise NLM and Work, Energy, Power, I will go through Collisions pretty thoroughly. but ya, i am pretty sure, this is one dimention

12. arindameducationusc

For 2D The equation is (don't ask me how as I haven't revised yet) is=> $m _{1}u _{1}\sin \alpha+m _{2}u _{2}\sin \beta=m _{1}v _{1}\sin \theta _{1}+m _{2}v _{2}\sin \theta _{2}$
