An automobile tire has a radius of 0.380 m, and its center moves forward with a linear speed of v = 18.0 m/s.
1. Decide the angular speed of the wheel.(Assume that there is no slipping of the surfaces in contact during the rolling motion.)
2. Relative to the axle, what is the tangential speed of a point located 0.175 m from the axle?
