You are told the speed is v0. ##\dot R## is only one component of that.Alexanddros81 said:

Angular speed, represented by the symbol ##\dotθ##, refers to the rate of change of the angular displacement of the arm OC over time. It is a measure of how fast the arm is rotating around point O.
The angular speed of the arm OC can be calculated by dividing the change in angular displacement (##Δθ##) by the change in time (##Δt##). This can be represented by the formula ##\dotθ = \frac{Δθ}{Δt}##.
Angular speed is typically measured in radians per second (rad/s) or degrees per second (°/s). The choice of unit depends on the unit used for angular displacement (radians or degrees) and the unit of time (seconds).
Angular speed refers to the rotational motion of the arm OC, while linear speed refers to the straight-line motion of a point on the arm. Angular speed is measured in radians or degrees per second, while linear speed is measured in meters or feet per second.
The angular speed of the arm OC can be affected by the length of the arm, the radius of rotation, and the force applied to the arm. Additionally, friction, air resistance, and the mass of the arm can also impact the angular speed.
