Question

show that s=ut + 1)2at square for uniform accelerated motion by any method​

Answer 1

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) -1
• from the veocity relation
• v=u+at -2
• substitute 1 in 2
• s=1/2t(u+u+at)
• =1/2t(2u+at)
• s=ut+1/2at^2

Hope it helps and pls mark it as the best.
