An object of mass m is at rest on a horizontal plane. The angle of inclination of the plane is slowly increased until the object starts to move. The coefficients of static and kinetic friction between the block and the incline are µs and µk

Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.15 times a second. a tack is stuck in the tire at a distance of 0.373 m from the rotation axis. noting that for every rotation the tack travels one circumference (a) find the tack's tangential speed. (b) what is the tacks radial acceleration?
