WebOct 1, 2013 · The linear (or tangential) speed of a point on a rotating object is given by. v = ω r, where ω is the angular speed (in rad/s = s -1) and r the distance between the point and the rotational axis. In this case, r is the radius and. v = (pi/7) s -1 (8 cm) = 8pi/7 cm/s. With 1 significant digit, this rounds to 4 cm/s.
