In the figure below there is one larger disc centred in O of radius 10 cm, a smaller disc centred in A of radius 3 cm, and an outer ring of neglectable thickness centred in O. The rod OA is fixed and cannot rotate, but the discs and the ring can rotate freely around their centres. If the rotation speed of the inner larger disc centred in O is 2500 rpm, find the angular speed of the upper point B which is part of the outer ring, in rad/s. 3

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
