the speed record for a hummingbird is about 50 mph or 22.3 meters/sec. If this world- record hummingbird is flying horizontally 1 meter above your head, how fast do you need to turn your head (or camera) to track it when it is: (i) 10 meters away from you (horizontally, not along the diagonal) (ii) at a 45-degree angle from your head? (iii) directly above your head? For each, give an answer in radians/sec, degrees/sec, and rotations/sec.
