Question

A bicyclist is riding a bicycle on a flat road.The combined mass of the bicyclist and bicycle is m= 110kg , the radius of each wheel is R= 32.5cm , and the coefficient of rolling resistance between the tires and the road is a = 0.160cm . The pedaling power of the bicyclist is translated to the back wheel through the tension in the chain that is wrapped around a set of gears. What is T, the tension in the chain that allows the bicycle to maintain a constant velocity when the chain is on the gear with a radius r= 3.75cm ? Consider the combined weight to be evenly distributed between the two wheels. Express your answer to three significant figures and include the appropriate units.

Explanation / Answer

Without offering the required solution, I have to intervene for two reasons :
(1) - The statement do not make sense as coefficient of friction is a bare dimentionless number: ".... and the coefficient of rolling resistance between the tires and the road is a = 0.190cm . "
(2) - With rolling wheels, the coefficient of rolling resistance between the tires and the road is out of consideration.
