Homework Help: Physics

an automobile tire has a radius of 0.350M, and its center forward with a liner speed of v=13.0m/s.
(a) Determine the angular speed of the wheel. (Assume that there is no slipping of the surfaces in contact during the rolling motion.)
(b) Relative to the axle, what is the tangential speed of a point located 0.175m from the axle?

Did you mean to write:
Its center MOVES forward at a LINEAR speed of 13.0 m/s"
(a)Let w be the angular roation speed of the wheel, abd R its radius. The linear speed of the center of a nonslipping wheel is given by
v = R w. Solve for w
(b) For any point on the wheel with radius r, the tangential speed is
v' = r w.
