Step 1: The assumption of "no external torque" allows us to assume conservation of angular momentum. Express this mathematically as Lᵢₙᵢₛᵢₐₗ and Lᵢₙₐₗ expand this statement using L = Iω.
step 2: In order to expand the "initial" and "final" moment of inertia and angular speed terms on both sides of the equation, complete the general version of the following equations/relationships:
What is the moment of inertia of a solid sphere of mass M and radius R? (Consider: Would the statement change if the sphere was not solid Would the solution to the problem change Answers below.)
I = [_______]
