Question

I don't understand this question 

**Problem 47:** A track is mounted on a large wheel that is free to turn with negligible friction about a vertical axis (Fig. 11-48). A toy train of mass *m* is placed on the track and, with the system initially at rest, the train's electrical power is turned on. The train reaches a speed of 0.15 m/s with respect to the track. What is the wheel's angular speed if its mass is 1.1 kg and its radius is 0.43 m? (Treat it as a hoop, and neglect the mass of the spokes and hub.) **Figure 11-48: Problem 47** The figure depicts a large, circular track resembling a hoop mounted horizontally. There appears to be a toy train on the track. The setup allows the wheel to rotate around a vertical axis with minimal friction. --- This problem involves concepts from rotational dynamics, exploring the conservation of angular momentum in a system where external torques are negligible.
