(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A photon of momentum P strikes a nucleus at rest and s absorbed. If The final (excited)

nucleus is M calculate its velocity.

2. Relevant equations

p = mv/(gamma)

3. The attempt at a solution

P = Mv/gamma

P^2 - (Pv/c)^2 = (M^2)(v^2)

P^2 = (Mv)^2 + (Pv/c)^2

V = P / sqrt( (M^2) + ((P^2)/(C^2)) )

The answer in the back is

P(C^2) / sqrt((M^4)(C^2) + P(C^2))
