Answer:-

From graph:-

BC = v -u.

OD = AC = t.

OA = u.

# refer the attachment for diagram

As you know area under velocity time graph is equal to displacement.

Now,

s = area \: of \: triangle + area \: of \: rectangle

s =  \frac{1}{2}  \times ac \times bc + od \times dc

Substituting the values.

s =  \frac{1}{2} (v - u)t + ut

as

(v - u) = at

s =  \frac{1}{2} at \times t + ut

s =  \frac{1}{2} a {t}^{2}  + ut

rearranging

s = ut +  \frac{1}{2} a {t}^{2}

Hence derived the second equation of motion.
