**Help!! Challenging rolling ball problem ahead!**

A solid sphere of rotational inertia I=2/5(MR^2) is rollling without slipping on a horizontal rough surface toward a rough inclined plane. The sphere's mass is 2kg and radius is 8 cm. The velocity of the sphere as it aproaches the incline is 10m/s.

Since I don't know how to put the incline here, well, it has an angle of elevation of 30, and the distance of the hypothenuse of such triangle is 12.

a) With what speed will the sphere reach the top of the incline assuming nos slippage on the incline either?

I'd appreciate if someone explains in detail this problem. Thx.
