A car has wheels of diameter 550 mm and is travelling along a straight road with a constant speed of 20 m/s. What is the angular velocity of the wheel?

A pulley attached to a shaft has a radius of 50 mm and rotates at 24 rev/s. What is the linear speed of the pulley belt wrapped round the wheel if no slippage occurs?
