A uranium nucleus (238U) moves along the positive ?-axis with speed ? = 5.0 × 105 m/s when it decays 92 ? into an ?-particle (4He, helium nucleus) and a thorium nucleus (234Th). If 4He moves off at an angle of 2 902 20.2° above the ?-axis with a speed ??? = 1.4 × 107 m/s, you will determine what is the recoil velocity, ? , of 234Th and the angle below the ?-axis. Assume the uranium-thorium-alpha system is isolated...
