Problem 1: Let us consider the Earth as a sphere rotating at some constant angular velocity about the axis through its poles. You, of mass m, are at some point on the surface of the Earth, at some angle 0 above the equator, as shown below: (a) What is the speed (not angular speed) at which you and your point are rotating about the polar axis? (b) In what kind of motion do you move, and what is the magnitude of the net force causing it? 3.

NEed help with the following problem

**Problem 1:** Let us consider the Earth as a sphere rotating at some constant angular velocity \(\vec{\omega}\) about the axis through its poles. You, of mass \(m\), are at some point on the surface of the Earth, at some angle \(\theta\) above the equator, as shown below: [Diagram Description: The diagram displays a circle representing the Earth, with a vertical line passing through its center representing the polar axis. The letter \(R\) denotes the Earth's radius. A point on the surface of the Earth above the equator is marked, and a line extending from the center of the Earth to this point creates an angle \(\theta\) with a horizontal line originating from the center. This horizontal line represents a projection of the radius \(R\). An arc with the angular velocity \(\omega\) is indicated near the top of the circle, showing the rotational direction around the polar axis.] **(a) What is the speed (not angular speed) at which you and your point are rotating about the polar axis?** _____ **(b) In what kind of motion do you move, and what is the magnitude of the net force causing it?** _____ The circle represents the Earth with its axis of rotation shown as a vertical line passing through the center, indicating the poles. The radius of the Earth is labeled as \(R\). The point where you are located on the Earth's surface is marked at an angle \(\theta\) above the equator. The diagram helps in understanding the rotational dynamics at a given point on the Earth's surface.
