The auto in Problem 12.11 has shown a sensitivity to yaw angle. At a yaw angle of 20°, the lift coefficient increased to 1.0. What is the lift force at 100 mph for this case?

Data From Problem 12.11

A 2007 Toyota Prius has a drag coefficient of 0.26 at road speeds, using a reference area of 2.33 m². Determine the horsepower required to overcome drag at a velocity of 30 m/s. Compare this figure with the case of head and tail winds of 6 m/s.
