Question

In the figure shown, the plank is being pulled to the right with a constant speed v. If the cylinder does not slip then

  1. the speed of the centre of mass of the cylinder is 2v    
  2. the speed of the centre of mass of the cylinder is zero    
  3. the angular velocity of the cylinder is v/R    
  4. the angular velocity of the cylinder is zero    

The correct answer is: the angular velocity of the cylinder is v/R
