The velocity at the first support is zero, the velocity calculated at the other end isdependent on the two unknown angular speeds. Use the fact the velocity at the other support is zero to calculate the two angular velocities. Similarly, use the two point formulafor acceleration to go from one support to the other.

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.
