Two bicycle tires are set rolling with the same initial speed of 3.50 m/s along a long, straight road, and the distance each travels before its speed is reduced by half is measured. One tire is inflated to a pressure of 40 psi and goes a distance of 18.8 m; the other is at 105 psi and goes a distance of 93.6 m. Assume that the net horizontal force is due to rolling friction only and take the free-fall acceleration to beg = 9.80 .m/s^2What is the coefficient of rolling friction M for the tire under low pressure?
