Problem 2. A cyclist is able to attain a maximum speed of U = 30 km/hr on a calm day. The total mass of rider and bike is m = 65 kg. The rlling resistance of the tires is FR = 7.5 N, the frontal area is A = 0.25 m2, and drag coefficient is %3D Cp = 1.2. (a) Determine the power the cyclist can produce with no wind. On a day with a wind speed of Verind = 10 km/hr, find the maximum speed the cyclist is able to attain cycling (b) into the wind and (c) with the wind.

Problem 2. A cyclist is able to attain a maximum speed of U = 30 km/hr on a calm day. The total mass of rider and bike
is m = 65 kg. The rolling resistance of the tires is FR = 7.5 N, the frontal area is A = 0.25 m2, and drag coefficient is
Cp = 1.2. (a) Determine the power the cyclist can produce with no wind. On a day with a wind speed of
Varind = 10 km/hr, find the maximum speed the cyclist is able to attain cycling (b) into the wind and (c) with the wind.
(d) Calculate and plot all three maximum speeds versus (use a range of 0.1 to 1.2) to consider the impact of using an
aerodynamic fairing (streamlining shell to guides the air around the cyclist) to reduce the drag coefficient. NOTE: Use
EES (Engineering Equation Solver) to solve this problem which requires iteration and make the plot. A tutorial is
available here a if you not familiar with EES.
