Question

derive the equation v = u+at as graphically

Answer 1

see the map in book plzzz i cannot able to make it

initial velocity u = OA         --------1
final velocity v = BC           --------2

BUT FROM THE GRAPHY
           BC=BD+DC
.:          V=BD+DC

AGAIN  DC=OA     -------3

SO   V=BD+OA
FROM EQ. 1 OA +U

.: V=BD+u    -------4

a=BD/AD
 BUT AD=OC=t

a=BD/t
at=BD        ---------5

SUBSTITUTING VALUE OF BD IN EQ.4

.: V=u + at
