Two rings O and O' are put on two vertical stationary rods AB and A'B' respectively as shown in figure. An inextensible string is fixed at point A' and on ring O and is passed through O' moves downwards at a constant speed v, find the velocity of the ring O in terms of `alpha`.

Two small rings O and O' are put on two vertical stationary rods AB and A'B', respectively. One end of an inextensible thread is tied at point A'. The thread passes through ring O' and its other end is tied to ring O. Assuming that ring O' moves downwards at a constant velocity v_(1) , then velocity v_(2) of the ring O, when /_AOO'=alpha is

Two small rings each of mass ‘m’ are connected to a block of same mass ‘m’ through inextensible light strings. Rings are constrained to move along a smooth horizontal rod. Initially system is held at rest (as shown in figure) with the strings just taut. Length of each string is ‘l’. The system is released from the position shown. Find the speed of the block (v) and speed of the rings (u) when the strings make an angle of theta=60^(@) with vertical. (Take g = 10 m//s^2 )

A ring of mass m = 0.3kg can slide freely on smooth vertical rod. A light and inextensible string is connected to the ring and passes over a smooth and fixed pulley as shown in the figure. The distance of the pulley from the rod is 0.8m and the other end of the string is connected to a block of mass M = 0.5kg. The ring is held in level with pulley and then released from rest. The distance by which the ring moves down before coming to rest for the first time is 0.75K. Find K.
