A basketball weighs 500grams or (.5 kg) it has a radius of 10cm (.10 m) and is rolling at 2.0 m/s. Find translational Ke Rotational Ke Translational momentum and Rotational momentum.

2. Relevant equations

translational ke= 1/2mv^2

rotational ke = 1/2Iw^2 ( I am unsure of what inertia equation to use for a basketball)

Translational momentum= mv^2

rotational ke = iw

3. The attempt at a solution

Translational ke = 1/2 mv^2= .5(.5kg)(2.0m/s)^2= 1 J

I think I know how to do the equations I just dont know what equation to use for the rotational inertia for a basketball, if someone could help me on that. Thanks
