sorry wrote it wrong

anonymous · Answer

I need help finding finial velocity v1' and v2' I just need an example problem or the formula

anonymous · Answer

I do not want the answer it just hard for me to understand can you help me

anonymous · Answer

In STR or where?

anonymous · Answer

? sorry i do not understand what STR means

anonymous · Answer

lets say I have a problem that gives me the initial velocities and mass but it wants me to find the finial velocities?

anonymous · Answer

Special theory of relativity,in that v1 is the velocity of source and v2 is the velocity of object.if any one of them coming towards other one then veloity will be added.

anonymous · Answer

We have to make up or own problem it gives me a hint saying solve for v2' the sub. this expression into first equations 
the equation that is given is for the after collision and before collision. 
m1v1+m2v2=m1v1'+m2v2'
