acceleration = a
initial velocity = u
final velocity = v
time = t
[tex] \sf t_1 = time \: of \: initial \: velocity \\ \sf t_2 = time \: of \: final \: velocity[/tex]
As we know
[tex] \sf \red {a = \frac{v - u}{t_2 - t_1} }[/tex]
so further
[tex] \sf a = \frac{v - u}{t} \\ \\ \sf at = v - u \\ \\ \sf v = u + at[/tex]
If we will make a velocity-time graph we will observe a linear curve
as shown in attachment
