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 v1, then velocity v2 of the ring O, when ∠AOO’=α

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 v1, then velocity v2 of the ring O, when ∠AOO’=α

the time of flight is found to be t. The acceleration with which the lift is moving up is Two small rings O and O' are put on two vertical stationary rods AB and A'B' When a body is thrown up in a lift with a velocity u relative to the lift
