Answer questions 1-3 & 5 in terms of M and I only. Assume the objects below rotate in the horizontal plane, start from rest and there is no friction. 1. Two identical balls each of mass M are connected by thin, massless rods as in the diagram. If the object is rotated about its left end, what is its rotational inertia? L 2. A third identical ball is added as in the diagram. If this new object is rotated about its left end, what is its new rotational inertia? L 3. The three balls are rearranged as in the diagram below. If this new object is rotated about the point shown, what is its new rotational inertia? L ddd. 4. Compare the Rotational Inertias of the objects in #2-3. Explain qualitatively (without reference to the actual rotational inertia math models) why this ranking makes sense. Answer questions 1-3 & 5 in terms of M and I only.
