Why is the run option greyed out here? What am I doing wrong with this function?

It is grayed out because you must call a function with inputs in a live script. See the note at the bottom of this page:
"Running live functions in the Live Editor using the Run button is only supported in MATLAB Online™. When you run a live function using the Run button, the output displays in the Command Window. To run a live function in an installed version of MATLAB, call the function from the Command Window or from a script or live script."
To test your functions in the live editor using the run button, add the following line before your functions. You will then be able to use the Run button.
Your nested function is never called by the parent function, so will never run.
Also, the point of a function is to call it with various inputs. Therefore, it should be unnecessary to define velocity, height, and angle inside your function when those are your input variables. Your code is replacing the input values with the hard coded values.
