ðŸ¤“ Based on our data, we think this question is relevant for Professor McGill's class at UF.

A size-5 soccer ball of diameter 22.6 cm and mass 426 g rolls up a hill without slipping, reaching a maximum height of 6.50 m above the base of the hill. We can model this ball as a thin-walled hollow sphere.

a) At what rate was it rotating at the base of the hill?

b) How much rotational kinetic energy did it then have?
