Rolling without slipping

A soccer ball of diameter $$22.6\text{ cm}$$ and mass $$426\text{ g}$$ rolls up a hill without slipping, reaching a maximum height of $$5\text{ m}$$ above the base of the hill. We can model this ball as a thin-walled hollow sphere. What was its translational speed at the base of the hill? Assume no energy loss by friction. Leave your answer to 2 dp.
