# Ring-Race

This question would amplify your skills in Kinematics.

Two rings O and O' are put two vertical stationary rods AB and A'B'. An inextensible thread is fixed at point A' and on the ring O and is passed through the ring O'. Assuming O' moves downwards constantly with $$v_{1}$$ , determine velocity $$v_{2}$$ if └AOO' is α. If the answer can be expressed as $$v_{1}$$a($$sin^c(\frac{α}{b}$$))/cosα. Find a+b+c
