Question

A pulley on a frictionless axle has the shape of a uniform solid disk of mass 2.50 kg and radius 0.150m. A 1.50 kg stone is attached to a very light wire that is wrapped around the rim of the pulley (Fig), and the system is
released from rest. (a) How far must the stone fall so that the stone has 1.20 m/s speed? (b) What percentage of the total kinetic energy does the pulley have?

The diagram illustrates a simple mechanical system consisting of a pulley and a stone. The key components are:

1. **Pulley**: The diagram shows a circular pulley labeled as "2.50 kg pulley." This indicates the mass of the pulley, which is an essential factor in calculating its moment of inertia and understanding the dynamics of the system.

2. **Stone**: Suspended below the pulley is an object labeled as "1.50 kg stone," indicating its mass. The stone is attached to a rope that runs over the pulley.

This setup is typical in physics problems related to rotational motion and dynamics. The pulley is used to change the direction of the force applied on the stone, which could be part of an experiment or demonstration involving topics such as Newton's laws, gravitational forces, or energy conservation. Understanding the mass of both the pulley and the stone is crucial for solving related equations and predicting the motion of the system.
