Uniform accelerated motion (UAM) equations, a.k.a. "kinematics equations":
Newton's second law:
For the tire at high pressure:
vf2 = v02 + 2aΔx
Two bicycle tires are set rolling with the same initial speed of 3.80 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 18.6m ; the other is at 105 psi and goes 92.6m . Assume that the net horizontal force is due to rolling friction only.
What is the coefficient of rolling friction (Uk) for the tire under high pressure?
