Question

Derive the formula v=u+at by graphical method.

Answer 1

Answer:

v=u + at

Explanation:

v=final velocity at B

u=initial velocity at A

a=acceleration from A to B

t=time taken to reach from A to B

<----------------------------t----------------------------->

A B

_________________________________________

u v

a

change in velocity=final velocity (v) -

initial velocity (u)

=v - u

so,

acceleration=change in velocity/time

=v - u / t

or, a = v - u / t

or, v - u = at

or, v =u + at (PROVED)
