Unformatted text preview: PHYS 260 Mid—term Test 7 Monday, October 25, 2010 1. Two particles, each with rest mass m0, approach each other along the line between them. One has total energy 2771002 and the other has total enefgy 3771062 , as measured in the lab frame. The
particles collide and make a single, massive, particle. (a) what is the rest mass of the new panicle? (b) what is the momentum, in the lab frame, of the new particle? CL) 4’7 {Wkﬂwiﬂgﬁ 'mel‘imézr
