A drag force on a car, with frontal area A = 2 m^2, driving at 80 km/h in air at 20°C is Fd = 0.225 A ρairV^2.

Question 1

A drag force on a car, with frontal area A = 2 m2, driving at 80 km/h in air at 20°C is Fd = 0.225 A ρairV2. How much power is needed and what is the traction force?

Question 2

W = FV

V = 80 km/h

A drag force on a car, with frontal area A = 2 m^2, driving at 80 km/h in air at 20°C is Fd = 0.225 A ρairV^2.
