**Problem Statement:**

A 93-kg firefighter slides down a fire pole starting from rest. The average frictional force exerted on him by the pole has a magnitude of 840 N. By the time he reaches the bottom of the pole, his speed is 3.6 m/s. Determine the distance he slid down the pole.

**Diagram Explanation:**

- The diagram shows the firefighter at the top and bottom of the pole.
- At the top, he is positioned before beginning his slide, marked by height \( h_0 \).
- At the bottom, his speed is labeled as \( v_f = 3.6 \, \text{m/s} \).

**Variables:**
- Mass of the firefighter: 93 kg
- Frictional force: 840 N
- Final speed: 3.6 m/s
- Initial speed: 0 m/s (rest position)
- Height/sliding distance: \( h_0 \) (to be determined)

This problem involves concepts of energy transformations and dynamics, specifically considering gravitational potential energy, kinetic energy, and work done against friction.
