The angular velocity Of the chainring will determine the linear speed at which the chain travels. The angular velocity of the sprocket depends upon the linear speed of the chain. The sprocket and real wheel rotate atbthe same rate, and the diameter of the wheel is 700 mm. The speed at which lance travels is determined by the angular velocity of his rear wheel.
When lance Armstrong blazed up mount ventoux in the 2002 tour, he was equipped with a 150 mm diameter chchainring and a 95 mm diameter sprocket. If he was peddling at a rate of 90 revolutions per minute, find his speed in kilometers per hour.
