Tyre of a bicycle has voulme `2xx10^(-3)m^(3)` Initially the tube is filled to `75%` of its volume by air at atmospheric pressure of `P_(0)=10^(5)N//m^(2)`. When a rider rides the bicycle the area of contact of tyre with road is `A=24xx10^(-5)m^(2)`. The mass of rider with bicycle is 120kg. The number of stokes which delivers, `V=500cm^(3)` volume of air in each stroke required to infalte the tyres is [Take `g=m//s^(2)`]
