Probably zero.. i know that its 5gr if i want to "loop the loop" - but i only want to reach the top..

Hi, i need to calculate the minimal velocity at point A to reach point B Not asked to complete full loop, There is no friction. I guess (mv^2)/2 = mg*2r >>> v = sqrt(4gr), my friend say v = sqrt(5gr) Thanks.
