Can anyone please help with the following tutorial question?

Use Scilab to solve the following problem. Think about how you verify your answer is correct (Hint: how do you check a solution to an equation?). A bullet of mass M = 2g has been shot vertically into the air and is falling back at its terminal velocity. The terminal velocity is determined by gM = Ddrag where g is acceleration due to gravity and M is the mass and Ddrag is the drag–a function of the terminal velocity. Expanding Ddrag in terms of the terminal velocity the drag equation can be written as

(2x9.81)/100 = 1.4 x 10^-5 x v^1.5 + 1.15 x 10^-5 x v^2

where v is the terminal velocity (ms-1). The first term on the right hand side is the frictional drag and the second term the drag due to pressure. Determine the terminal velocity of the bullet to three decimal places.

Explanation / Answer

Mass is often confused with weight. Mass is the measure of the amount of matter in an object;
it depends only on the type and number of atoms in it. In SI units it is measured in kilograms.
Weight on the other hand is not a fixed property of an object but depends on the amount of
gravitational force acting on it, hence it varies with location.
Weight is directly proportional to the acceleration due to gravity. In SI units
weight = mass " acceleration due to gravity.
