An 8.90-cm-diameter, 310 g sphere is released from rest at the top of a 2.00-m-long, 17 degree incline. It rolls, without slipping, to the bottom.(adsbygoogle = window.adsbygoogle || []).push({});

a) What is the sphere's angular velocity at the bottom of the incline?

b) What fraction of its kinetic energy is rotational?

If someone could help me out, it'd be great...I'm not exactly sure how to tackle this problem...
