7) Determine the momentum of the residual nucleus left behind after the radioactive decay event. Include a labelled vector diagram of the system after the radioactive decay event in your solution. 8) Two ice skaters undergo a collision, after which their arms are intertwined and they have a common velocity of 0.85 m/s [27 S of E]. Before the collision, one skater of mass 71 kg had a velocity of 2.3 m/s [12 N of E], while the other skater had a velocity of 1.9 m/s [52 S of W]. What is the mass of the second skater? 7) Determine the momentum of the residual nucleus left behind after the radioactive decay event.
