(a) At what launch angle greater than 54.0° does the golf ball just barely miss the top of the tree in front of the green? Assume that the ball has an initial speed of 13.5 m/s, and that the tree is 3.00 m high and is a horizontal distance of 14.0 m from the launch point.

(b) Where does the ball land in the case described in part (a)?

(c) At what launch angle less than 54.0° does the golf ball just barely miss the top of the tree in front of the green?

(d) Where does the ball land in the case described in part (c)?
