Answer 1

Answer:

A body begin to move with initial velocity u to describe a distance s with an acceleration a. After time t it's get final velocity v

from the relation,v=u+at

squring both sides, We get

V2=(u+at)2

V2=U2+2.u.at+(at)2

=U2+2a(it+1/2at2)

V2=U2+2as [s=ut+1/2at2]

A body begin to describe with initial velocity u.it attain it's final velocity v after a time t with an acceleration a

from the definition of acceleration

acceleration=rate of change of velocity

=change of velocity by total time taken

=final velocity-inital velocity by total time taken

• I,e a=v-u by t

at =v-u

v=u+at
