Q7. Rotational Dynamics (20 points): A big hollow spherical shell of radius 2m and a mass of 1 kg is rolling down a hill as shown below. It started rolling from v = 0 at the top of the hill. a 50 m 20 m a) What is the moment of inertia of the hollow spherical shell? b) Using conservation of energy find the velocity of the sphere at point A. c) What is the rotational kinetic energy of the sphere at point A? d) If the object did not roll (considering only translational motion), find the velocity at point A
