Jane wants to estimate the drag coefficient of herself on herbicycle. She measures the projected frontal area to be 0.40 m2and the rolling resistance to be 0.80 N . s/m. The mass ofthe bike is 15 kg, while the mass of Jane is 80 kg. Jane coasts down a long hill that has a constant 4° slope. (SeeFig. ) She reaches a terminal (steady-state) speed of14 m/s down the hill. Estimate the aerodynamic drag coefficient CD of the rider and bicycle combination.

Question
Jane wants to estimate the drag coefficient of herself on her
bicycle. She measures the projected frontal area to be 0.40 m2
and the rolling resistance to be 0.80 N . s/m. The mass of
the bike is 15 kg, while the mass of Jane is 80 kg. Jane coasts down a long hill that has a constant 4° slope. (See
Fig. ) She reaches a terminal (steady-state) speed of
14 m/s down the hill. Estimate the aerodynamic drag coefficient CD of the rider and bicycle combination.
