Question 26

In a fluid dynamics experiment, the drag coefficient DDD of a specialized underwater drone is modeled as a function of its velocity vvv (in m/s) by the expression:

D(v)=32v2−14v+54v−1 D(v) = \frac{32v^2 - 14v + 5}{4v - 1} D(v)=4v−132v2−14v+5​

The expression can be written in the form:

D(v)=Av+B+C4v−1 D(v) = Av + B + \frac{C}{4v - 1} D(v)=Av+B+4v−1C​

where A,BA, BA,B, and CCC are constants. State the value of AAA.
