The drug coefficient `C_(v)` of an automobile is determined from the experssion `C_(D)=(D)/((1)/(2)pv^(2)S)`   Where D is the drag force experimentally determined in a wind tunnel, p is the air density, v is the speed of the air in the wind tunnel, and S is the cross-sectional area of the car presented to the air flow. Determine the dimension of `C_(D)` in lenght.
