Moment of inertia for ball rolling up a ramp.
1. The problem statement, all variables and given/known data
A ball with mass 1.0 kg and radius 0.20m rolls without slipping along level ground with a speed of 10 m/s. The ball then rolls up an incline reaching a maximum vertical height of 8.0 m. What is the moment of inertia of the ball? (Do not assume the ball is a uniform sphere).
2. Relevant equations
3. The attempt at a solution
Since I really have no clue on where to start this one. I guess I'll focus in on that since it's not a uniform sphere I can still assume it's a ball and use the above formula to plug it in and solve it right?
It comes out to 0.016

Think of a general important principle that you could use to solve this problem.
