Two bicycle tires are set rolling with the same initial speed of 3.40 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 18.2 meter; the other is at 105 psi and goes a distance of 93.8 meter. Suppose that the net horizontal force is due to rolling friction only and take the free-fall acceleration to be g = 9.80 m/s2. Find the coefficient of rolling friction for the tire under low pressure?
