An automobile tire has a radius of 0.430 m, and its center moves forward with a linear speed of v = 14.0 m/s.
(a) Determine the angular speed of the wheel. (Assume that there is no slipping of the surfaces in contact during the rolling motion.)
rad/s
(b) Relative to the axle, what is the tangential speed of a point located 0.175 m from the axle?
m/s
