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 +3.9 m/s, grabs and holds onto him so that they move off together with a velocity of +2.3 m/s. If the mass of the tackler is 125 kg, determine the mass of the receiver in kilograms. Assume momentum is conserved. kg
