Back on Earth, a ball is thrown off a roof top with a horizontal velocity 8 m/s and a downward vertical velocity 5 m/s. It hits the ground 2.2 s later. What is the direction at which the ball hits the ground? Give the angle the velocity vector makes with vertical (straight down = 0° and horizontal = 90°). Use g = 9.8 m/s if needed and neglect air friction. Read carefully -- there are versions of this question with upward vertical velocity and another with downward vertical velocity.

Question
![Back on Earth, a ball is thrown off a roof top with a horizontal velocity 8 m/s and a downward vertical velocity
5 m/s. It hits the ground 2.2 s later. What is the direction at which the ball hits the ground? Give the angle
the velocity vector makes with vertical (straight down = 0° and horizontal = 90°).
Use g = 9.8 m/s² if needed and neglect air friction.
