Question

Hunter’s velocity was 4.5 m/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.

Answer 1

His acceleration is zero.

Acceleration = change in velocity / time. Since his initial and final velocities are the same (4.5 m/s), the change in velocity is zero, so the acceleration is zero.
