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

The best description of Hunter's movement is: <br /><br />**His acceleration is zero.**<br /><br />Since his velocity remained constant at \(4.5 \, \text{m/s}\) throughout the race, there was no change in velocity, which means his acceleration is zero. Acceleration is defined as the rate of change of velocity with respect to time. If the velocity does not change, the acceleration is zero.
