Answer 1

$\huge\underline{\overline{\mid{\bold{\red{ANSWER}}\mid}}}$

We all know that,

accelaration is the rate of change of speed per unit time.

rate of change of speed = $v-u$

formula for accelaration is,

$a = \frac{v - u}{t} \\ = > at = v - u \\ = > at + u = v \\ = > v = u + at$

Hence, Proved
