10.9 A radioactive nucleus (mass = 1.70*10-26 kg) is at rest. It suddenly decays (explodes) into three pieces. One piece has mass mi = 5.00*10-27 kg and is found to be moving along the +y axis with a speed of 6.00* 10 m/s. A second piece with mass m2 = 8.40*10-27 kg moves along the +x axis with a speed of 4.00* 10° m/s. Assuming the mass is held constant, find the velocity of the third and final piece that...
