1. A basketball can be modeled as a thin walled spherical shell with a mass of 0.600 kg and a radius of 12.0 cm. The ball rolls on a horizontal court at a speed 0f 0.70 m/s.
(i) What is the linear or translational kinetic energy of the ball?
(ii) What is the rotational kinetic energy of the ball?
(iii) If the speed of the ball is doubled, would the ratio of the rotational to translational kinetic energy INCREASE, DECREASE, or STAY THE SAME?
