hunters velocity was 4.5 m/s. at the end of his race, his velocity was the same. which best describes his movement?\no his movement stopped.\no his acceleration is zero.\no his time was constant.\no his acceleration was positive.
Answer
Brief Explanations:
Acceleration is the rate of change of velocity. Since Hunter's initial and final velocities are the same (4.5 m/s), there is no change in velocity. According to the formula $a=\frac{\Delta v}{\Delta t}$, where $\Delta v = v_f - v_i$ (final - initial velocity), and $v_f=v_i$, so $\Delta v = 0$. Thus, acceleration $a = 0$.
Answer:
His acceleration is zero.
