Homework Help: Rolling Friction and Bicycle Tires, Mastering physics problem.

  1. Oct 8, 2006 #1
    Information given:

    Two bicycle tires are set rolling with the same initial speed of 3.60 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 {\rm psi} and goes a distance of 18.1 m; the other is at 105 {\rm psi} and goes a distance of 93.1 m. Assume that the net horizontal force is due to rolling friction only and take the free-fall acceleration to be g = 9.80 m/s^2.

    Question 1:

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

    i really dont have a clue about this question.
