Question

1)Establish the relation: v²-u²=2as, using velocity time graph of the body. 2)A person goes to market, makes purchases and comes back at a constant slower speed. Draw displacement-time and velocity-time graphs of the person.

Answer 1

s(distance) =
average speed×time
s=u+v/2×t
u+v/2×v-u/a
since T=v-u/a
then,s=v2-u2/2a
2as=v2-u2
it's 1st one
hope this answer helps u...

Answer 2

this is the graph for above question no.1
