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.

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.

his acceleration was zero

Explanation:

when the last speed and the first speed are same, the acceleration becomes zero ... accelaration=first speed-last speed/time ... here a=4.5-4.5/time=0/time=0
