A device consisting of four heavy balls connected by low-mass rods is free to rotate about an axle, as shown in Figure 11.101. It is initially not spinning. A small bullet traveling very fast buries itself in one of the balls. m = 0.002 kg, v = 550 m/s, M1 = 1.2 kg, M2 = 0.4 kg, R1 = 0.6 m, and R2 = 0.2 m. The axle of the device is at the origin 0, 0, 0 , and the bullet strikes at location 0.155, 0.580, 0 m. Just after the impact, what is the angular speed of the device? Note that this is an inelastic collision; the system's temperature increases.
