You throw a vall toward a wall with a speed of 25m/s and at an angleof 40 degree above the horizontal. The wall is 22m from the realease point of the ball. a) How far above the release point does the ball hit the wall? b) What are the horizontal and vertical components of its velocity as it hits the wall? c) When it hits has it passes the highest point on its trajectory?

I am confused...
