When an object with a weight of Mg falls vertically in the air, it is not only affected by gravity, but also by a resistance f which is proportional to the square of the velocity. Its size f = kV ^ 2, K is a positive constant. Then the final velocity of the falling object (that is, the velocity of the object when it finally moves at a constant speed) is______ .

Do uniform motion, that balance, acceleration is 0
If f = mg-kv2 = 0, the solution is the size of V
