1. A disc of moment of inertia 1.8 kg.m2 is rotating at a constant angular velocity of 3.2 rad.s-1. Another disc of moment of inertia 0.6kg.m2 initially at rest falls onto the first disc and the two rotates as a system. Which of the following statement(s) is/are true of this sprocess?
(i) The angular velocity for this process is conserved
(ii) The initial angular momentum of the first disc before the second disc fell on it is 5.76 kg.m2.s-1
(iii) The angular momentum of the system is conserved.
