Question

prove the equation v =u+at mathematically and also graphically

Answer 1

here is your answer for the equation

Answer 2

Above figure represents a velocity_time graphics in Which AB represents initial velocity (u), CE represents final velocity (v), such that change in the time ( t) represented by side AE To prove v=u+at, acceleration =slope of graphBC therefore a=CE_DE/BD or a=v_u/t therefore v - u=at OBSERVE THE ABOVE FIGURE CAREFULLY
