In what distance will a car traveling with 100 kn stop if a force of -200n is applied?

The descriptions of both the car's motion and of the proposed action are
defective, so the question is unanswerable.

-- The car's motion could be described in terms of its speed or its kinetic
energy, but "100 kN" is meaningless as a description of motion.

-- To describe a force as negative ("-200N") is meaningless as long as
neither a frame of reference nor a positive direction has been defined.

If you're looking for an even spread of clay, silt and sand, add a considerable amount of sand and some clay until the 3 even out". soil texture triangle. silty clay loam soil is approximately 20 percent or less sand, 25 to 40 percent clay, and 40 to 70 percent silt.
