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.

Question

For the instant shown in the figure, the angular velocity and the angular acceleration, of the bar AB, is 3 rad / sec and 5 rad / sec2, respectively.
