In a football game, a receiver is standing still, having justcaught a pass. Before he can move, a tackler, running at a velocityof +3.77 m/s, grabs him. The tackler holds onto the receiver, andthe two move off together with a velocity of +1.64 m/s. The mass ofthe tackler is 87.0 kg. Assuming that momentum is conserved, findthe mass of the receiver.
