You should be more specific with your question. A lot of people don't know what a v-t graph is (velocity-time).\n\nAnyway, it's a horizontal line. Velocity remains constant while time keeps moving forward.

Extreme position! \nBecause acceleration is directly propotional to the displacement from the mean position and directed opposite to it.\n\na=-(ω^2)x

D. The road.\n\nIf you draw a free-body diagram you'll see a frictional force vector pointing in the direction of motion.

on a graph every point has an x and y coordinate.  The vertical(up-down) is the Y-coordinate, the horizontal (left-right) is the x-coordinate

It will look like a < with lines of slope 1 and -1.  The leftmost point will be at (0,-1).

a. = gradiant scale, because you can choose degrees (gradiants) between one pole and the other pole.\n\nb. = binary scale, because you only have two choices and can only select one of them\n\nc. = defined gradiant, because each of the degrees (gradiants) is pre-defined for you.\n\nI hope this is the best answer.

It comes from the fact that the "hypotenuse" of the two "triangles" is not a straight line segment.  It is actually two segments of similar, but not equal, slope.
