Guys - NOT SOF but you all are wrong. I reviewed the question and saw it was written - A ball has started from a hill. Where will it be the fastest or where is the most kinetic energy so it is A. point W. If it was from which point should it start to reach the flag the fastest it would be D

Well, isn't Option A the place where it slows down 'cause that's the point where the low slope starts so I thought it would be point X (Option B)
