A plane flying at 600 km/h on a straight horizontal course 5 km above the ground passes directly ovver an observer who is watching the plane through a telescope. How fast is the telescope rotating (a) at that moment? (b) one minute later?

This is one of those things that I can't quite remember how to do. It's in my calculus textbook, which is unfortunately at home.
It's a fun problem, though, I'll tell you that. |
