Question

A home run is hit in such a way that the baseball just clears a wall 25.0 m high, located a distance 125 m from home plate. The ball is hit at an angle of 38.0° above the horizontal, and air resistance is negligible. (Assume the ball is hit at a height of 1.0 m above the ground.)

You have still not asked a question. If it is about initial launch velocity, see

and use the same approach.
