Question 13 (2 points)
What is the magnitude of the drag force (N) on a Hummer H2 travelling on a
highway at a constant velocity of 85 km/h?
Use the information provided below to answer the question:
Toyota Camry Drag area = 0.70 m²; Toyota Camry Drag coefficient = 0.28
Hummer H2 Drag area = 2.50 m²; Hummer H2 Drag coefficient = 0.64
Density of air, $\rho$ = 1.21 kg/m³
$\boxed{F_D = \frac{1}{2}C\rho A v^2}$
Drag force is,
