Question

using the concept of distance time graph drevie relation v= u + at​

Answer 1

Answer:

Consider a velocity - time graph for a body moving with uniform acceleration 'a'. The initial velocity is u at A and final velocity is v at B in time t.

Perpendicular lines BC and BE are drawn from point B to the time and velocity axes so that the initial velocity is OA and final velocity is BC and time interval is OC. Draw AD parallel to OC.

We observe that

BC = BD + DC = BD + OA

Substituting BC = v and OA = u

We get v = BD + u

or, BD = v - u

As we know

acceleration=change in velocity/time

a = BD/AD= BD/OC

or, a = v-u/t

at = v-u

at +u = v
