A boy rides his bicycle which has wheels with a radius of 30.0 cm. If the boy on the bicycle accelerates from rest to a speed of 10.0 m/s in 10.0 s, what is the angular acceleration of the tires?
A cyclist is riding such that the wheels of the bicycle have a rotation rate of 3.0 rev/s. If the cyclist brakes such that the rotation rate of the wheels decrease at a rate of 0.3 rev/s2, how long does it take for the cyclist to come to a complete stop?
Calculate the angular velocity of the rotational motion of the Earth around its axis.
