**Problem Description:**

A cylinder of mass \( M = 8\ \text{kg} \) and radius \( R = 20\ \text{cm} \) slides down a frictionless hill from height \( H = 10\ \text{m} \). At the bottom of the hill, there is a plane with a friction coefficient \( \mu = 0.25 \).

**Questions:**

a) How far will the cylinder slide along the plane before it begins to roll smoothly?

b) What will be the final speed of the center of mass of the cylinder?

**Diagram Explanation:**

The diagram shows a hill with a height of 10 meters. A cylindrical object is placed at the top. The hill has a frictionless surface labeled as "No friction." Once the cylinder reaches the bottom, it moves onto a flat plane where friction is present, indicated by "Friction."

---

The diagram represents the setup for a physics problem involving the motion of a cylinder under the influence of gravity and friction. Students are expected to use principles of energy conservation and rotational motion to solve the questions.
