1.	A woman of mass m stands at the edge of ,a solid cylindrical platform of mass M and radius R. At t = 0 the platform is rotating with negligible friction at angular velocity omega_(0) about a vertical axis passing through the centre. The woman begins to walk with speed v, relative to the platform, towards the centre of the platform:
Answer» Angular VELOCITY when WOMAN reaches the centre is `(V+ m/M)omega_(0)` Angular velocity as function of time is `omega=(M+m)/(M+2m(1-vt//R)^(2))` Energy of SYSTEM is conserved Momentum of woman increases in magnitude Answer :A::B::D
