Question details

3.) (12 Points The drag force, F, imposed by the surrounding air on an automobile moving with velocity V is given by where C is a constant called the drag coefficient, A is the projected frontal area of the vehicle, and p is the air density. For C-0.42, A -2m2, andp 1.23kg/m2, (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. Note: For partb, derive the formula for the power in terms of the vehicle velocity V Then plot the drag force for the given range of velocities using an Excel spreadsheet. Ans. Part a.) P- 11 .07 kw
