Two discs of moments of inertia `I_1` and `I_2` about their respective axes (normal to the disc and passing through the centre), and rotating with angular speed `omega_1` and `omega_2` are brought into contact face to face with their axes of rotation coincident. What is the loss in kinetic energy of the system in the process?

Two dics of moments of inertia I_1 and I_2 about their respective axes (normal to the disc and passing through the centre), and rotating with angular speed omega_1 and omega_2 are brought into contact face to face with their axes of rotation coincident. Calculate the loss in kinetic energy of the system in the process.

Two dics of moments of inertia I_1 and I_2 about their respective axes (normal to the disc and passing through the centre), and rotating with angular speed omega_1 and omega_2 are brought into contact face to face with their axes of rotation coincident. Account for this loss.

Two discs of moments of inertia I_(1) and I_(2) about their respective axes (normal to the disc and passing through the centre), and rotating with angular speed omega_(1) and omega_(2) are brought into contact face to face with their axes of rotation coincident . What is the angular speed of the two-disc system ?

Two dics of moments of inertia I_1 and I_2 about their respective axes (normal to the disc and passing through the centre), and rotating with angular speed omega_1 and omega_2 are brought into contact face to face with their axes of rotation coincident. Find the angular speed of the two-disc system.

The discs of moments of inertia I_1 and I_2 about their respective axis (normal to the disc and passing through the centre), and rotating with agnular speeds omega_1 and omega_2 are brought into contact face to face with their axis of rotation coincident. Show that the kinetic energy of the combined system is less than the sum of the initial kinetic energies of the two discs. How do you account for this loss in energy ? Take omega_1 ne omega_2 .

Two discs of moments of inertia I_1 and I_2 about their respective axes normal to the disc and passing through the centre and rotating with angular speeds omega_1 and omega_2 are brought into contact face to face with their axes of rotation coinciding. Then the angular speed of the two disc system is
