The earth rotates about an axis passing through its north and south poles with a period of one day. If it is struck by meteorites, then
Two discs of moments of inertia I1 and I2 about their respective axes (normal to the disc and passing through the centre), and rotating with angular speeds I1 and I2 are brought into contact face to face with their axes of rotation coincident. What is the angular speed of the two disc system?
