To find the desired frequency of revolution of a given body when moving in a circle, we will use the formula: V = 2 * Π * R * ν, whence we express: ν = V / (2 * Π * R).
The values of the variables: V is the linear velocity of the body (V = 12 m / s); R is the radius of the circle (R = 3 cm = 0.03 m).
Calculation: ν = V / (2 * Π * R) = 12 / (2 * 3.14 * 0.03) = 63.69 Hz.
Answer: The frequency of rotation of a given body is 63.69 Hz.
