A camera is watching the flight of a projectile fired straight up from 250 feet away. The height of the projectile t seconds after it is fired is 16^2 + 600 + 2 feet. Find the rate of change of the angle of elevation of the camera 5 seconds after the projectile is fired.

Going through related rates in Calc 1 right now, and I've been doing ok. But this problem has really got me stuck for whatever reason, with the diagram and everything. It reminded me of projectile motion from physics, but I wasn't sure if that type of diagram would work for related rates. Was wondering if maybe a different perspective would help. Thank you.
