A ball is thrown from the top of a building upward at an angle of 55 degrees to the horizontal and with an initial speed of 9 m/s, as within the figure. The ball is thrown at a height of 55 m above the ground and hits the ground 21.6089 m from the stub of the building. The acceleration of gravity is 9.8 m/s^2 . What is the speed of the ball just before it strikes the ground? Answer within units of m/s.
