Hunter’s velocity was 4.5 m/s. At the end of his race, his velocity was the same. Which best describes his movement?
A. His movement stopped.
B. His acceleration is zero.
C. His time was constant.
D. His acceleration was positive.

his acceleration was zero

Explanation:

when the last speed and the first speed are same,the acceleration becomes zeroaccelaration=first speed-last speed\time...here a=4.5-4.5\time=0\time=0

We can describe Hunter's movement by the statement B. his acceleration is zero.

Acceleration is defined as the rate of change of velocity. Hunter's velocity is constant, which means that it did not change over the considered period of time. When the change in velocity is zero, the acceleration is also zero. If his acceleration was positive, his final velocity would be greater than 4.5 m/s, and if it were negative, then his final velocity would be less than 4.5 m/s.

Explanation:

life will not be easy it will be filled with war, lack of resources, damaged planet, and lack of land to live on.

i imagine life will be easier in the sense that we will have better technology and better health and medical advances as well as infustructure growth and economic resilliance we will have much stronger militaries and probably be constintly fighting with other countries for resources and lang that is actually cleanenough to live or farm on . as well i think the need for fresh water will only brainliest answer lol

b and d
