A tire 0.500 m in radius at a constant rate of 200 rev/min.Find the speed and acceleration of a small stone lodged in the tread of the tire( on its outer edge).

    I assume you want the speed relative to the axle. The velocity with respect to the ground depends upon the angular location of the stone.

    w = 20.94 radians/s

    V = R*w = 10.47 m/s

    a = R*w^2 = 219 m/s^2
