A person is standing on top of a building. While standing at the edge of the building the person throws a water balloon downward with a speed of 14 m/s and at an angle of 44° below the horizontal. It takes 2.9 s for the water balloon to hit the person's friend. (a)  How high is the building in meters?  (b)  How fast is the water balloon moving when it hits the friend on the ground? Give your answer in m/s.  (c)  What was the horizontal distance between the friend on the ground and the building in meters?
