Question
A block of mass M is tied to one end of a massless rope. The other end of the rope is in the hands of a girl of mass 2 M as shown in the figure. The block and the girl are resting on a rough wedge of mass M as shown in the figure. The whole system resting on a smooth horizontal surface. The girl pulls the rope. Pulley is massless and frictionless. What is the displacement of the wedge when the block meets the pulley. (Girl does not leave her position during the pull)
- 0.5 m
- 1 m
- zero
- 2/3m
The correct answer is: 0.5 m
