The mass of the two players together will be (147+m) kg, where m is the mass of the quarterback. Remember that to get the mass, you can just divide the momentum by the velocity. (147 + m) = (698.25 kg m/s)/(2.6 m/s) 147 + m = 268.55 kg and subtract 147 from both sides and round your answer to get 122 kg (3 significant figures).
