A truck has a frontal area of 12 m². Its coefficient of drag is C = 0.8. Gravitational acceleration is 9.8 m/s² 1(a) (10 pts.) At sea level, where the air density is 1.225 kg/m³,the truck can go at most 20 m/s up an 7% grade with a loaded mass of 21,000 kg (including the truck). What is the truck's maximum power in kilowatts? 1(a) 1(b) (10 pts.) In Twin Peaks, Washington, the density of air is only 1.05 kg/m². In Twin Peaks, what is the fastest speed the truck can maintain while climbing a 9% grade and weighing 24,000 kg? A truck has a frontal area of 12 m². Its coefficient of drag is C = 0.8.
