Question

using velocity time graph prove that V2=u2 +2as formula where the symbol have their usual meaning.​

Answer 1

Answer:

to find the distance (s) with help of a graph ..........

first we need to find area of trapezium

=(OA+BC)OC/2

where OA=u,BC=vand OC=t

s=(u+v)/t

but we know from 1 equation that t=(v-u)/a

so by this s=(u+v)(v-u)/2a

s=v^2-u^2/2a

2as=v^2-u^2
