Explain how you could use the construction tool or a compass and straightedge to create a line segment that is twice as long as ("ab" ) ̅.

answer:

the construction has the following steps,

step 1:   adjust the compass according to the length of the segment ab,

step 2: make a line that seems greater than the twice of the segment ab in length,

step 3 : make an arc from end of the line on the line,

step 4 : from the intersection of the arc and the line make another arc on the line.

thus, we get a line segment from the end point of the line to the final arc on the line which is doubled to the line segment ab.

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.
