Answer 1

Answer:

a = v-u/t this the formula of acceleration

Answer 2

Answer:

Suppose a body moving from A to B with initial velocity u and at point B it's velocity is v called it final velocity , also time taken by body travel from A to B is t.

so,

acceleration $= \frac{final \: velocity - initial \: velocity}{time \: taken}$

or , $a =v-\frac{u}{t}$

→ it's SI unit is ${m}/{s}^2$
