How many swings n must be made in order to, using a pump that captures a volume of v = 40 cm3 of air during each swing, fill the chamber of a bicycle wheel with a volume of V = 2000 cm3 so that the area of its contact with the road is S = 60 cm2 at a pressure force wheels on the road F = 350 H? At the initial moment, the chamber is filled to 0.75 volumes at atmospheric pressure. Atmospheric pressure p0 = 1.013·105 Pa.
