sanya55: can I do by integration?

skh2: yes you can. but using a graph plz

skh2: i mean calculation can be done by integration

sanya55: integration is not by graph

skh2: well as you like you can do.. plz help

sanya55: graphical method is too long

sanya55: so can I give by integration?

skh2: okk no problem

sanya55: okk

Answer:

graph for derivation

we know : displacement = area under the velocity time graph .

S= area of trapezium ACEF

S= 1/2 ( b¹ + b² ) h

s= 1/2 ( AF+CE )FE

S= 1/2 ( U+ V) T

We know -v= u+ at

v-u/a= t

now 2 in 1

S= 1/2( v+u) (v-u)

2as= ( v+u) (v-u)

2as=v²-u²

[v² - u2 = 2as]

hope it will help u
