Question

shiw the graphical proof of s=ut-1/2 at^2​

Answer 1

Answer:

Let us suopose that an object in uniform acceleration 'a' and it has covered the distance 's' within time 't' .The distance

covered by the object during time 't' is given by the area of quandrangle DOEB

s= area of quandrangle DOEB

= area (rectangle DOEA) + area (triangle DAB)

s = (AE×OE)+1/2 × ( AB+DA)

But AE=u

OE =t (OE=DA=t)

AB=at (AB=CD)

s = u ×t + 1/2 × at × t

Newton second equation of motion....

s=it +1/2 at^2

Hope it helps ...
