The 52-kg reel has a radius of gyration about its center O of ko = 240 mm. If it is released from rest, determine the total external work done to it when its center O has traveled 7.2 m down the smooth inclined plane (with angle = 28°). Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point, and proper Sl unit. Take g = 9.81 m/s².

Question
**Problem Description:**

The 52-kg reel has a radius of gyration about its center \( O \) of \( k_O = 240 \) mm. If it is released from rest, determine the total external work done to it when its center \( O \) has traveled 7.2 m down the smooth inclined plane (with angle \(\theta = 28^\circ\)). Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point, and proper SI unit. Take \( g = 9.81 \, \text{m/s}^2 \).

**Diagram Explanation:**

The diagram shows a reel on an inclined plane. Important measurements and details include:

- Angle of inclination (\(\theta\)) is 28 degrees.
- The larger outer radius of the reel is 0.4 m.
- A smaller radius of 0.2 m is marked from the center of the reel to a point on the inclined plane.

These measurements are critical for understanding the geometry and mechanics involved.
