I need help with my online school work cause I’m in quarantine

I think it is personally 2.

Work: (  2 times 2 )  Divided by 2 )

The formula for area is Length multiplied by the Width. so your answer should be 4

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.

i belive those are the ones that are under 90 degreese.
