Challenge Problems
Push your limits with challenges.
Question 1
A racing car with a frontal area of 1.8 m² travels at a speed of 80 km/h. Calculate its drag force if the air density is 1.2 kg/m³ and the drag coefficient is 0.3.
💡 Hint: Ensure all units are consistent before calculation!
Question 2
Discuss how varying the diameters of an object, while keeping its length constant, influences drag forces encountered in fluid environments.
💡 Hint: Reflect on how shapes interact with fluid dynamics and the elements involved.
