Which of the following is being constructed in the image? a. a line parallel to a given line through a point not on the lineb. a line perpendicular to a given line through a point not on the linec. a line segment that is congruent to a given line segmentd. a perpendicular bisector of a line segment

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
