State and proof the equation of motion v=u+at ,v²-u²=2as ,s=ut+1/2at²

Answer»

E R :s = UT + (at^2 / 2)E X P L A N A T I O N :Actually you can DERIVE the second equation usingv^2 - u^2 = 2as …..(Eqn. 1) ANDV = u + at ….(Eqn. 2), here’s how…take value of “v” from equation 2 and substitute in Equation 1, and REARRANGE:Equation 1 becomes,(u + at)^2 - u^2 = 2asu^2 + 2uat + (at)^2 - u^2 = 2as2uat + (at)^2 = 2asCancelling 2A on both sides…s = ut + (at^2 / 2)
