For the position of button we can use force balance as
Friction Force = Centripetal force
so here we will have
here we know that
R = radius of circle where button is placed
f = 35 rev/min
now from above equation
so friction coefficient will be 0.33
A thin uniform rod has a length of 0.480 m and is rotating in a circle on a frictionless table. The axis of rotation is perpendi

<h3>What is the center of mass?</h3>- The center of mass, sometimes referred to as the balancing point in physics, is the only location where the weighted relative position of the distributed mass accumulates to zero.
- Here is where a force can be applied to produce a linear acceleration without also producing an angular acceleration. When calculations in mechanics are made about the center of mass, they are frequently made simpler. It is a fictitious location where one can suppose that an object's full mass is concentrated to see its motion.
- In other words, to apply Newton's equations of motion, the center of mass is the particle equivalent of the provided item.
