You are riding in the Tour de France and are out in the front of the pack. The implication of riding at the front is that you experience lots of air resistance! The good news is that the weather report indicates it is a completely calm day, i.e. the wind speed is zero. Using the assumption that at high bike speed (which is true if you're leading the Tour de France) almost all the pedal power is used to counter air resistance and not rolling resistance, what will be your velocity (in m/s) if you are producing 350 W of power? You can assume an air temperature of 20°C, and the bike and rider have a frontal area of 0.43 m² and a drag coefficient of 0.7.
