A uniform sphere has a moment of inertia of 2/5*M*R 02, where M = 10 kg and R0 is 10 cm. a. Beginning at rest, the ball is spun around its center of mass by pinching the opposite sides of the sphere and applying a tangential force of 5 N in opposite directions on opposite sides. What is the angular acceleration of the sphere due to these two applied torques? b. If the sphere is rotated by 20 degrees by the applied torques, what is the work that is done on the sphere? c. What is the angular velocity of the ball after being spun? d. What is the rotational kinetic energy of the ball after being spun?
