InterviewSolution

1.	show that S =ut + 1/2 at square
Answer» Consider an object which has travelled displacement s in the time t under uniform acceleration a.Let intial velocity of the object be u and the final velocity v.s=1/2t(u+v)-1from the veocity relationv=u+at -2substitute 1 in 2s=1/2t(u+u+at)=1/2t(2u+at)s=ut+1/2at^2
