Question
A seagull flying horizontally over the ocean at a constant speed of 3.00 m/s carries a small fish in its mouth. It accidentally lets go of the fish, and 2.10 s after letting go the fish lands in the ocean.
(a) Just before reaching the ocean, what is the horizontal component of the fish's velocity in meters per second ? Ignore air resistance. Assume the bird is initially traveling in the positive xdirection. (Indicate the direction with the sign of your answer.)
(b) If the seagull's initial speed were decreased, which of the following regarding the fish's velocity upon reaching the ocean would be true? (which ones apply.)
The horizontal component of the fish's velocity would decrease.
The horizontal component of the fish's velocity would increase.
The horizontal component of the fish's velocity would stay the same.
The vertical component of the fish's velocity would decrease.
The vertical component of the fish's velocity would increase.
The vertical component of the fish's velocity would stay the same.
Explanation / Answer
(a) Neglecting air friction. horizontal speed will remain the same as 3.00 m/s i^
(b) Using the same logic, If the seagull's initial speed were decreased
--->The horizontal component of the fish's velocity would decrease.
