Question

Relation between angular velocity and coefficient of friction

Answer 1

Answer:

So μ = mg / N = mg / ma = g / a. ... Now you have an equation for the coefficient of static friction (μ) in terms of the radius (r) and the angular velocity (ω), which you know. You'll need to convert your angular velocity from revolutions per second to radians per second before substituting for g, r and ω.
