Question

State velocity-time relation in uniformly accelerated motion. Use graphical method to obtain this relation.

Answer 1

Answer:

here

let the initial velocity be u.let the body start moving with acceleration a and coveres s distance in time t....

...now by V-t graph.......

.....1) acceleration a = slope of the line AB

= tanthetha....

see picture...

2)distance covers by body in the second is equal to ...= area of traingle ABC + Aare of rectangle OACE

hence proved.......
