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
- the speed of the centre of mass of the cylinder is 2v
- the speed of the centre of mass of the cylinder is zero
- the angular velocity of the cylinder is v/R
- the angular velocity of the cylinder is zero
The correct answer is: the speed of the centre of mass of the cylinder is zero

One ice skater of mass m moves with speed 2v to the right, while another of the same mass m moves with speed v toward the left, as shown in figure I. Their paths are separated by a distance b. At t = 0, when they are both at x = 0, they grasp a pole of length b and negligible mass. For t > 0, consider the system as a rigid body of two masses m separated by distance b, as shown in figure II.
