Question

Refer to the picture below.

**Physics Experiment: Friction Applied to a Spinning Bike Wheel** A 1.3 kg bike wheel is spinning at 190 rpm clockwise when a student applies a frictional force as shown in the diagram. The moment of inertia for any ring (such as a bike tire, neglecting the spokes) is given by \( I = mr^2 \). *Answer all questions relative to the center of the wheel.* ### Questions and Input Fields: 1. **Initial Angular Speed (in selectable units):** - **Input Field**: [ ] rad/s 2. **Torque Caused by Friction:** - **Input Field**: [ ] N·m 3. **Moment of Inertia:** - **Input Field**: [ ] kg·m² 4. **Angular Acceleration:** - **Pre-Filled Input Field**: 1625 rad/s² 5. **Time for Wheel to Stop Spinning:** - **Input Field**: [ ] s 6. **Rotation Distance Before Stopping:** - **Input Field**: [ ] rad - **Input Field**: [ ] revolutions ### Diagram Explanation: - **Diagram**: On the right side of the text, there is an overhead view of a bike wheel. - **Visualization**: - The wheel's outer rim is marked in green. - Radial lines extend from the center to the circumference, indicating the spokes (though we neglect them in calculations). - An arrow labeled "2.4 N" points tangentially to the wheel’s perimeter, indicating the direction of the applied frictional force. - The diameter of the wheel is labeled with a measurement of 10 cm on the top.
