During a football game, a receiver has just caught a pass and is standing still. Before he can move, a tackler, running at a velocity of 3.70 m/s, grabs and holds onto him so that they move off together with a velocity of 2.00 m/s. If the mass of the tackler is 123 kg, determine the mass of the receiver. Assume momentum is conserved.
