An object is thrown straight up. At the same instant that the object reaches its maximum height, a second object is dropped from this maximum height. Which object hits the ground first and why?

Also, a ball is thrown straight up. If the ball's initial velocity is considered positive, what is the acceleration of the ball while ascending? And how would you draw a vector diagram for this problem? Help me please! thanks.

Well i think that the one that is dropped from the maximum height will hit the ground first because it doesn't have negative velocity like the one thrown from the ground has.
