The figure shown is an overhead view of a thin uniform rod of length L and mass M rotating horizontally at angular speed ω about an axis passing through its centre. A particle of mass m initially attached to the end A is ejected from the rod with velocity Vp which is perpendicular to the rod at the instant of ejection. If ω=10.0 rad s-1, L=1.0m, m=M and Vp is 4 m s-1 more than the speed of rod end A just after the ejection, then the value of Vp is

Consider the shown diagram. A fixed vertical smooth rod AB is kept in front of a uniform disc of mass m and radius R which is rolling without slipping on a rough horizontal surface. Velocity of centre of disc is 3 m s-1. A rod PQ of length 2 m is connected with disc at Q, (point Q is at a vertical distance of R2 from centre of disc) by pin joint and other end of rod PQ can freely slide over smooth vertical rod AB. At this instant rod PQ makes an angle θ=150° with rod AB as shown. Find the angular velocity of rod at this instant.
