Question

A stationary bicycle wheel of radius 0.7 m is mounted in the vertical plane (see figure below). The axle is held up by supports that are not shown, and the wheel is free to rotate on the nearly frictionless axle. The wheel has mass 4.3 kg, all concentrated in the rim (the spokes have negligible mass). A lump of clay with mass 0.5 kg falls and sticks to the outer edge of the wheel at the location shown. Just before the impact the clay has speed 8 m/s, and the wheel is rotating clockwise with angular speed 0.27 rad/s. Assume +x is to the right, +y is upward, and +z is out of the page. Assume the line connecting the center to the point of impact is at an angle of 45° from the horizontal.Just after the impact, what is the angular velocity (magnitude and direction) of the wheel?

The image depicts a simple mechanical system involving a wheel and a particle. Here's a detailed breakdown:

1. **Components**:
   - **Wheel**: A circular wheel with several spokes, centered at point **C**.
   - **Particle**: A small mass denoted by **m**.

2. **Notation**:
   - **R**: Represents the radius of the wheel.
   - **M**: Represents the total mass of the wheel.

3. **Motion**:
   - The particle **m** is shown moving with an initial velocity **v** towards the wheel.

4. **Diagram Explanation**:
   - The particle is positioned above the wheel, on the left side, indicating that it's approaching or colliding with the wheel.
   - The dashed line indicates the direction of the particle's velocity vector **v**.

This system can illustrate principles of dynamics, such as momentum and energy transfer, in educational contexts focused on mechanics.
