(1) A circular wheel has a radius R = 0.45 + or - 0.02 m. The wheel is observed to be rotating uniformly with period T = 2.00 +or- 0.05 s.
(i) Compute the frequency with which the wheel spins.
(ii) Compute the angular speed of the wheel.
(iii) Compute the tangential speed of points on the rim of the wheel.
