if velocity is positive, which would most likely yield a negative acceleration?\na final velocity that is faster than an initial velocity.\na time that is less than a half hour.\nan initial velocity that is faster than a final velocity.\na time that is greater than a half hour.

if velocity is positive, which would most likely yield a negative acceleration?\na final velocity that is faster than an initial velocity.\na time that is less than a half hour.\nan initial velocity that is faster than a final velocity.\na time that is greater than a half hour.

Answer

Explanation:

Step1: Recall acceleration formula

Acceleration $a=\frac{v_f - v_i}{t}$, where $v_f$ is final - velocity, $v_i$ is initial - velocity, and $t$ is time.

Step2: Analyze for negative acceleration

For $a$ to be negative, since $t>0$ (time is non - negative in this context), we need $v_f - v_i<0$, which means $v_i>v_f$.

Answer:

C. An initial velocity that is faster than a final velocity.
