If A is the projected area of a vehicle in square metres, V is speed of the vehicles in kilometres per hour and C is a constant, then the wind resistance R to the moving vehicles, is given by

[A]. R = CAV
[B]. R = CAV2
[C]. R = CAV3
[E]. R = C2AV

Please explain the solution.

A is the transverse cross-sectional area of vehicle and v is the velocity of the vehicle.
So wind resistance is directly proportional to A and square of velocity constant C is introduced to have a relationship between R, A and V.

C is the constant.

In case does not mention to take 1 value.
