initial velocity = ulet acceleration = alet length of train = 2lhence :: v²= u² - 2*a*(2l)==> v² + u² = 2* a*(2l) ==> 2*a*(l) = (1/2)*(v² + u² ) now let the velocity with which the mid point of train passes the pole be "" V"" therefore ,==> V² = u² - 2*a*(l)==> V² = u² - [ (1/2)*( v² + u²) ]==> V² = u² - v²/2 - u²/2==> V² = (2u² - v² - u²)/2==> V² = ( u² + v²)/2==>. V =√( u² + v² )/√2

initial velocity is u and final is v. Let the length of train be 's' or the distance covered be 's'.So by 3rd kinematical eqn we getv^2-u^2=2as...(1)Now for the midpoint let the velocity be 'x' so by the same equation we getx^2-u^2=2as/2=as...(2)By equating eqn 1 n 2 we get, x^2-u^2=v^2-u^2/2Now we want 'x' so after you solve you will get x=(v^2+u^2/2)^1/2
