Question

a car moves with a constant velocity of 5 m/s. as time goes on, its acceleration...
options: decreases, is zero, not enough info, increases

Explanation:

Acceleration is defined as the rate of change of velocity. For an object moving with constant velocity, the change in velocity over time is 0. Substituting into the acceleration formula $a=\frac{\Delta v}{\Delta t}$, where $\Delta v = 0$, the acceleration equals 0.

Answer:

is zero
