A bicyclist is riding a bicycle on a flat road. (Figure 2) The combined mass of the bicyclist and bicycle is = 110 , the radius of each wheel is = 32.5 , and the coefficient of rolling resistance between the tires and the road is = 0.170 . 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 , the tension in the chain that allows the bicycle to maintain a constant velocity when the chain is on the gear with a radius = 3.75 ? Consider the combined weight to be evenly distributed between the two wheels.Express your answer to three significant figures and include the appropriate units.
