Question

A 97.9 kg97.9 kg horizontal circular platform rotates freely with no friction about its center at an initial angular velocity of 1.55 rad/s1.55 rad/s. A monkey drops a 9.51 kg9.51 kg bunch of bananas vertically onto the platform. They hit the platform at 4545 of its radius from the center, adhere to it there, and continue to rotate with it. Then the monkey, with a mass of 20.5 kg20.5 kg, drops vertically to the edge of the platform, grasps it, and continues to rotate with the platform. Find the angular velocity of the platform with its load. Model the platform as a disk of radius 1.73 m1.73 m.

**Problem Description:**

A 97.9 kg horizontal circular platform rotates freely without any friction about its center at an initial angular velocity of 1.55 rad/s. A monkey drops a 9.51 kg bunch of bananas vertically onto the platform. They hit the platform at \( \frac{4}{5} \) of its radius from the center, adhere to it there, and continue to rotate with it. Then the monkey, with a mass of 20.5 kg, drops vertically to the edge of the platform, grasps it, and continues to rotate with the platform.

**Task:**  
Find the angular velocity of the platform with its load. Model the platform as a disk of radius 1.73 m.

**Calculation Field:**  
- **Angular velocity:** [Input box] `rad/s`
