Question

write formula to find out displacement of a body if its velocity changes from u to v and acceleration a

Answer 1

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

here s= displacement

hope it will help u

Answer 2

to find the relation which you have asked
you should use
s=ut+1/2at^2
and
v^2=u^2+2as
where a is acceleration
v is final velocity
u is initial velocity
t is time
s is displacement
hope it will help you dear ☺
