Aerospace engineers sometimes compute the trajectories of projectiles such as rockets. A related problem deals with the trajectory of a thrown ball. The trajectory of a thrown by a right fielder is defined by the (x,y) coordinates as displayed in the Figure below.

Find the appropriate initial angle θ₀ , if v₀
= 30m/s, and the distance to the catcher is 90 m. Note that the throw leaves the right fielder’s hand at an elevation of 1.8 m and the catcher receives it at 1 m. Also, you have to write your Matlab code.
