along a long, straight road? Two bicycle tires are set rolling with the same initial speed of 3.90 m/s along a long, straight road.?
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 17.8 m; the other is at 105 psi and goes a distance of 94.0 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
*What is the coefficient of rolling friction mu_r for the tire under low pressure?
I am really bad at physics so as much detail as possible about how you solve the problem would be great, thanks!
