A uniform ball with diameter of 10 cm rolls without slipping on a horizontal tabletop. The moment of inertia of the ball about an axis through its center is 2.2  10-3 kg  m2,
 
  and the translational speed of its center is 0.45 m/s.
  (a) What is its angular speed of the ball about its center of mass?
  (b) What is the rotational kinetic energy of the ball?
  (c) What is the ball's angular momentum about its center of mass?

Question 2

A negatively-charged plastic rod is brought close to (but does not touch) a neutral metal sphere that is connected to ground.
 
  After waiting a few seconds, the ground connection is removed (without touching the sphere), and after that the rod is also removed. The sphere is now A) negatively charged.
