Question

A small rock with mass 0.22 kg is released from rest at point A, which is at the top edge of a large, hemispherical bowl with radius R = 0.58 m . Assume that the size of the rock is small compared to R, so that the rock can be treated as a particle, and assume that the rock slides rather than rolls. The work done by friction on the rock when it moves from point A to point B at the bottom of the bowl has magnitude 0.22 J. Between points A and B, how much work is done on the rock by the normal force? Between points A and B, how much work is done on the rock by gravity? What is the speed of the rock as it reaches point B? Of the three forces acting on the rock as it slides down the bowl, which (if any) are constant and which are not? Explain. Just as the rock reaches point B, what is the normal force on it due to the bottom of the bowl?

The diagram illustrates a hemispherical bowl with two blocks, labeled A and B, placed on its inner surface. 

Key elements of the diagram include:

- **Bowl**: A cross-sectional view of the bowl is shown. It is hemispherical in shape.
  
- **Block A**: Located on the left side of the bowl. It appears to be affixed or stationery at that position.

- **Block B**: Positioned at the bottom of the hemisphere, directly at the lowest point. 

- **Arrow Representing Velocity (v)**: A green arrow extends horizontally to the right from Block B, indicating the direction of motion for the block. This shows that Block B may be moving or experiencing force in that direction.

- **Radius (R)**: A black arrow labeled R extends from the center of the hemisphere to an inner point on the surface of the bowl, illustrating the radius of the bowl.

Overall, this diagram could represent a physical scenario involving motion or forces acting within a hemispherical container and is likely aimed at explaining concepts such as motion dynamics or forces in a physics context.
