The drag force, Fd, imposed by the surrounding air on an automobile moving withvelocity
Chapter 1, Problem 1.52D(choose chapter or problem)
The drag force, \(F_d\), imposed by the surrounding air on an automobile moving with velocity V is given by
\(F_d= C_{d} A \frac{1}{2} \rho V^2\)
where \(C_d\) is a constant called the drag coefficient, A is the projected frontal area of the vehicle, and \(\rho\) is the air density. For \(C_d = 0.42, A = 2 \ \mathrm{m}^2\), and \(\rho = 1.23 \ \mathrm{kg/m}^3\), (a) calculate the power required (kW) to overcome drag at a constant velocity of 100 km/h, (b) compute and plot the required power (kW) to overcome drag as a function of velocity, for V ranging from 0 to 120 km/h.
