Question

proof that a=v-u/t if v means final velocity,a means acceleration,and u means initial velocity​

Answer 1

Let a, be acceleration of the body in motion, t- the time taken for the body from the starting point to the point of halt. Also let the initial and final velocities of the body be u and v respectively.

Therefore by definition,

Acceleration is the rate of change of velocity.

Symbollicaly;

a = (v-u)/t

By cross multiplication we get,

at = v-u, Making v the subject of the formula we get;

u + at = v

on re-arranging,

v = u + at .

Hence proved.
