An automobile tire has a radius of 0.280 m, and its center moves forward with a linear speed of v = 18.0 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?

i got a which was 64.2857 but cant figure out part b
