Hi everyone I am have done part of this problem but i am wondering how you would go about it:(adsbygoogle = window.adsbygoogle || []).push({});

A ball of mass M and radius R1 on the end of a thin massless rod is rotated in a horizontal circle of radius Ro about an axis of rotation AB.

a. Considering the mass of the ball to be concentrated at its center of mass, calculate its moment of inertia about AB.

b. Using the parallel axis theorem and considering the finite radius of the ball, calculate the moment of inertia of the ball about AB.

c. Calculate the percentage error introduced by the point mass approximation for R1 = 10 cm and Ro = 1.0m

I am having difficulty with these problems, I was wondering what you would suggest?

Thanks a lot.
