if velocity is positive, which would most likely yield a negative acceleration?\no a final velocity that is faster than an initial velocity.\no a time that is less than a half hour.\no an initial velocity that is faster than a final velocity.\no a time that is greater than a half hour.
Answer
Brief Explanations:
Acceleration is calculated as $a=\frac{v_f - v_i}{t}$, where $v_f$ is final velocity, $v_i$ is initial velocity and $t$ is time. If $v_i>v_f$ (initial velocity is faster than final velocity), then $v_f - v_i<0$. Since time $t>0$, acceleration $a$ will be negative. Time values alone do not determine the sign of acceleration. A final velocity faster than initial velocity gives positive acceleration.
Answer:
An initial velocity that is faster than a final velocity.
