I am confused...

The horizontal component of velocity, which remains constant is

Vox = 25 cos 40 = 19.15 m/s. The time of flight before it hits the wall is 22 m/19.15 m/s

t = 1.148 s.

The initial vertical velocity component is

Voy = 25 sin 40 = 16.07 m/s

(a) For the height y of the vertical impact point, solve

y = Voy t - (g/2) t^2

(b) The vertical velocity component at time t is

Vy(t) = Voy - gt

The horizontal component is Vox

(c) If Vy(t) <0, the ball has passed through maximum trajectory
