The air drag force on a car is 0.225 A ρV^2. Assume air at 290 K, 100 kPa and a car frontal area of 4 m^2 driving at 90 km/h. How much energy

Question 1

The air drag force on a car is 0.225 A ρV2. Assume air at 290 K, 100 kPa and a car frontal area of 4 m2 driving at 90 km/h. How much energy is used to overcome the air drag driving for 30 minutes?

Question 2

W = F ∆x = 676 N x 45 000 m

= 30 420 000 J = 30.42 MJ

The air drag force on a car is 0.225 A ρV^2. Assume air at 290 K, 100 kPa and a car frontal area of 4 m^2 driving at 90 km/h. How much energy
