I was wondering if someone could look over the steps to ensure I'm on the right track and provide me with any feedback!

Is this your solution or someone else's? If yours, it looks professional. I have not put in the numbers, but it looks right.

This is my own attempt at a solution for the question asked above

See edited post #4. If you wish to check your work, plug in the time of flight in the kinematic equations and see if the ball lands where you thought it would be.

Arithmetic errors creep in here:

but they do not affect the final results to 2sf, and otherwise it looks good.

All those long decimal numbers don't look good to me. This is why algebra was invented.
