I Review | Constants
Two bicycle tires are set rolling with the same initial
speed of 3.9 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 18.6 m
; the other is at 105 psi and goes a distance of 92.4
Correct
Correct answer is shown. Your answer 0.03129 was either rounded differently or used a different number of
significant figures than required for this part.
m. Assume that the net horizontal force is due to
Part B
rolling friction only and take the free-fall
acceleration to be g = 9.8 m/s? .
What is the coefficient of rolling friction ur for the second tire (the one inflated to 105 psi)?
