In the annual battle of the dorms, students gather on the roofs of Jackson and Walton dorms to launch water balloons at each other with slingshots. The horizontal distance between the buildings is 37.0 m, and the heights of the Jackson and Walton buildings are, respectively, 13.0 m and 21.0 m. The first balloon launched by the Jackson team hits Walton dorm 1.80 s after launch, striking it halfway between the ground and the roof. Ignore air resistance. (a) Find the direction of the balloon's initial velocity. Give your answer as an angle (in degrees) measured above the horizontal.

In the annual battle of the dorms, students gather on the roofs of Jackson and Walton dorms to launch water balloons at each other
with slingshots. The horizontal distance between the buildings is 37.0 m, and the heights of the Jackson and Walton buildings are,
respectively, 13.0 m and 21.0 m. The first balloon launched by the Jackson team hits Walton dorm 1.80 s after launch, striking it
halfway between the ground and the roof. Ignore air resistance. (a) Find the direction of the balloon's initial velocity. Give your answer
as an angle (in degrees) measured above the horizontal. (b) A second balloon launched at the same angle hits the edge of Walton's roof.
Find the initial speed of this second balloon.
