Question
6. A seagull flying horizontally over the ocean at a constant speed of 3.05 m/s carries a small fish in its mouth. It accidentally lets go of the fish, and 1.70 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? Ignore air resistance. Assume the bird is initially traveling in the positive x direction. (Indicate the direction with the sign of your answer.)
_____________ m/s
(b) Just before reaching the ocean, what is the vertical component of the fish's velocity? Ignore air resistance. Assume upward is the positive y direction and downward is the negative y direction. (Indicate the direction with the sign of your answer.)
____________ m/s
(c) If the seagull's initial speed were decreased, which of the following regarding the fish's velocity upon reaching the ocean would be true? (Select all that 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) Just before reaching the ocean, what is the horizontal component of the fish's velocity
(a) Vx = 3.05 m/s
(b) Just before reaching the ocean, what is the vertical component of the fish's velocity
(b) Vy = gt = -9.8m/s² * 1.7s = - 16.66 m/s
What is the initial y-component of velocity of the fish
0 m/s
What constant acceleration relation will allow you to find the final y-component of velocity
v = a * t =
