A device consisting of four heavy balls connected by low-mass rods is free to rotate about an axle. It is initially not spinning. A small bullet traveling very fast buries itself in one of the balls. In the diagram, m = 0.005 kg, v = 450 m/s, M₁ = 1.2 kg, M2 = 0.5 kg, R₁ = 0.8 m, and R2 = 0.3 m. The axle of the device is at the origin < 0, 0, 0 >, and the bullet strikes at location < 0.274, 0.752, 0 > m. M1 • m M2 R2 f M2 M1 Just after the impact, what is the angular speed of the device? Note that this is an inelastic collision; the system's temperature increases. angular speed (absolute value of the angular velocity) = radians/s
