Acceleration vs time graph would show C. A horizontal line (at zero)
Explanation:
The acceleration of an object is the rate of change of velocity of the object:
[tex]a=\frac{\Delta v}{\Delta t}[/tex]
where
[tex]\Delta v[/tex] is the change in velocity
[tex]\Delta t[/tex] is the time interval
For an object moving at constant velocity,
[tex]\Delta v = 0[/tex]
This means that also the acceleration is zero:
[tex]a=0[/tex]
And therefore, if we plot the graph of the acceleration vs time, we would see a horizontal line (cosntant acceleration) at zero (because the acceleration is zero).
