Question

Two bicycle tires are set rolling with the same initial speed of 4.0 m/sm/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 psipsi and goes a distance of 17.2 mm ; the other is at 105 psipsi and goes a distance of 92.9 mm . Assume that the net horizontal force is due to rolling friction only and take the free-fall acceleration to be ggg = 9.8 m/s2m/s2 .

What is the coefficient of rolling friction μrμrmu_r for the tire under low pressure?

I Review I Constants
Two bicycle tires are set rolling with the same initial speed of 4.0
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 17.2 m ;
the other is at 105 psi and goes a distance of 92.9 m . Assume
that the net horizontal force is due to rolling friction only and take
the free-fall acceleration to be g = 9.8 m/s2 .
