The areodynamic drag force is given by the expression:

D=CDS.5ρv2

where CD is dimensionless, S is a refrencearea (mL), ρ is the mass per unit volume of the gas, and v is the velocity of the object relative to the gas.

a) Suppose that the value of D is 800 when S, ρ, and vare expressed in SI base units. By converting units determine the value of D when S, ρ, v are expressed in U.S customary units.

b) the drag force D is in newtons when the expresssion is evaluated using SI units and is in pounds when the expression is evaluated in U.S comtumary units. using ur results from

a)determine the conversion factor from newtons to pounds.
