Special Relativity

A photon of energy E collides with a stationary particle of rest mass m0 and is absorbed. What is the velocity of the resulting composite particle?

NOTE: I used consrvation of momentum: p(before) = p(after), therefore p/c (energy of photon) = gamma*m0*v and solved for v. Apparently this is incorrect????  #### Earn Coin
