Question

ELECTRODYNAMICS (SEE CONSERVATION LAWS AND RELATIVITY CHAPTERS IN GRIFFITHS).

9- A large ball with mass M is originally at rest. To set the ball in motion we make smaller balls inellastical collide with the M ball. The smaller balls stick in M. There's a point in which we have thrown n smaller balls. Thus, the Mass of the bigger ball is now Mn, having velocity vn. vww 1, Derive a formula for the 4 vector momentum. (hint: conservation laws) 2 How do you generally determine the speed from a 4-momentum? 3 Combine these results to find the speed Vn.

Answer 1

this Mn- M is mass of n small balls and v is speed of small balls thrown intially
