A cyclist accelerates so that the tire goes from the angular speed of 1rad/s to an angular speed of around 3rad/s as he travels as he travels 18m on the road. (Suppose the tire rolls devoid of slipping). The tire's diameter is around 0.6m.
i) Find out the angular acceleration?
ii) Determine how long did it take to go the 18 m?
iii) Find out the tangential acceleration of a point on the thread?
