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 3.1 m/s, grabs and holds onto him so that they move off together with a velocity of 1.8 m/s. If the mass of the tackler is 115 kg, determine the mass of the receiver in kilograms. Assume momentum is conserved.
