1. The problem statement, all variables and given/known data You hold a small ice cube near the top edge of a hemispherical bowl of radius 100 mm. You release the cube from rest. What is the magnitude of its acceleration at the instant it reaches the bottom of the bowl? Ignore friction. 2. Relevant equations a=v^2/r delta U= delta Krot +delta Ktrans 3. The attempt at a solution mgR=1/2Iw^2+1/2mv^2 a=v^2/r So I'm not sure if it is so far so good. How do I find the rotational inertia here? How should I approach this question.
