Two bicycle tires are set rolling with the same initial speed of3.70 m/s along a long, straight road, and the distance each travelsbefore its speed is reduced by half is measured. One tire isinflated 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 93.3 m . Assume thatthe net horizontal force is due to rolling friction only and takethe free-fall acceleration to be g = 9.80 m/s2 .
a)What is the coefficient of rolling friction μr forthe tire under low pressure?
