Explanation:
All but kg can be vector quantities.
m/s^2 is acceleration. in the formula F = m*a the acceleration has direction and that means that force has direction. If you place an object on a table, there are 2 vectors in operation: one tends to move down (gravity) and one points up (the table top). The object would like to move but cannot, because the forces are equal but in opposite directions.
meters can be a vector or the unit of a vector. It is called displacement when it has direction.
km / hr. Since meters can be a vector, so can km. This is a velocity (or can be). When the direction is not specified, km/hr is a speed. It might describe the movement of a snail. hours really have no direction. hours can't go up, or down or left or right, the way km can. So hours add nothing to the question.
kg are units of mass. Mass really has no direction associated with it. Don't confuse mass and weight. Weight does have a direction, but mass does not.
