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

Options

  1. AThe speed of the centre of mass of the cylinder is 2 v
  2. BThe speed of the centre of mass of the cylinder is v
  3. CThe angular velocity of the cylinder is v R
  4. DThe angular velocity of the cylinder is zero

Correct answer

C. The angular velocity of the cylinder is v R

Step-by-step solution

For no slip condition velocity of plank = velocity of bottom point of sphere. ω = v R and v c = 0
