DRIVING An automobile moving at 12 meters per second on level ground begins to decelerate at a rate of 1.6 meters per second squared. The formula for the distance an object has traveled is d(t) = vt + at^2, where v, is the initial velocity and a is the acceleration. For what value(s) of t does d(t) = 40 meters?

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.

what are the things "represented below"?

step-by-step explanation:

nobody can if you dont give the choices
