Challenge Problems
Push your limits with challenges.
Question 1
A cyclist in an Olympic race generates a drag force of 10 N while traveling at 15 m/s with a frontal area of 0.4 m². Determine their drag coefficient.
💡 Hint: You need air density for calculations and substitute all values.
Question 2
If a building's design reduces drag coefficient from 1.2 to 0.8 in a windstorm, calculate the difference in drag force felt by a building with 60 m² frontal area at 20 m/s wind speed.
💡 Hint: Remember to use the same air density value for both calculations.
