Two circular discs A and B are of equal masses and thickness but made of metal with densities dA and dB (dA>dB). If their moments of inertia about an axis passing through their centres and perpendicular to circular faces are IA and IB, then A mass m1 moves with a great velocity. It strikes another [...]
