Question

Find the coefficient of kinetic friction between the axe and the grindstone.

The image depicts a sharpening stone being used, highlighting the forces and motion involved in the process.

### Description:
- **Sharpening Stone (Grindstone)**: The orange wheel represents the grindstone.
- **Mass**: The grindstone has a mass \( m = 50.0 \, \text{kg} \).
- **Force**: A force \( F = 160 \, \text{N} \) is applied to the surface of the grindstone.
- **Angular Velocity**: The grindstone rotates at an angular velocity represented by the symbol \(\omega\).

### Diagram Explanation:
- **Hands and Tool**: Two hands are shown holding a tool, pressing it against the grindstone, illustrating how force is applied in physical sharpening processes.
- **Force Arrow**: A red arrow indicates the direction of the force \( F \) applied to the grindstone.
- **Rotation Arrow**: A black curved arrow above the grindstone denotes its direction of rotation.

### Application:
This image assists in understanding the physics behind rotational motion, force application, and mechanical work in the context of sharpening tools.

Casting molten metal is important in many industrial processes. Centrifugal casting is used for manufacturing pipes, bearings, and many other structures. A variety of sophisticated techniques have been invented, but the basic idea is as illustrated in Figure P4.35. A cylindrical enclosure is rotated rapidly and steadily about a horizontal axis. Molten metal is poured into the rotating cylinder and then cooled, forming the finished product. Turning the cylinder at a high rotation rate forces the solidifying metal strongly to the outside. Any bubbles are displaced toward the axis, so unwanted voids will not be present in the casting. Sometimes it is desirable to form a composite casting, such as for a bearing. Here a strong steel outer surface is poured and then inside it a lining of special low-friction metal. In some applications, a very strong metal is given a coating of corrosion-resistant metal. Centrifugal casting results in strong bonding between the layers. Suppose a copper sleeve of inner radius 2.10 cm and outer radius 2.20 cm is to be cast. To eliminate bubbles and give high structural integrity, the centripetal acceleration of each bit of metal should be at least 100g. What rate of rotation is required? State the answer in revolutions per minute.

Two students are conducting an experiment in which they are trying to find a relationship between the angle of incline of a ramp and the final speed a car reaches when rolling down the ramp. In order to collect their data, the students must determine the final speed of the car at the bottom of the ramp. The students discuss how they should determine this speed. Student 1: “We need to measure the length of the ramp and the time it takes the car to roll down it. Then we can divide the total distance by the total time to find the final speed.” What is wrong with Student 1’s method for determining the final speed? This method will only determine the average speed, not the final speed. This method will determine the acceleration, not the final speed. This method does not account for the height of the ramp. This method does not take into account the angle of the ramp.
