Air resistance: An 80.0-kg object is falling and experiences a drag force due to air resistance. The magnitude of this drag force depends on its speed, v, and obeys the equation F_drag = (12.0 N ∙ s/m)v + (4.00 N ∙ s²/m²)v². What is the terminal speed of this object? A) 6.45 m/s B) 72.2 m/s C) 34.2 m/s D) 12.6 m/s E) 47.3 m/s
