An eagle is flying horizontally at 7.9 m/s with a fish in its claws. It accidentally drops the fish.(adsbygoogle = window.adsbygoogle || []).push({});

(a) How much time passes before the fish's speed doubles?

(b) How much additional time would be required for the fish's speed to double again?

Initial velocity in the x direction is 7.9m/s. I assumed final velocity in x direction was 7.9m/s and acceleration was 0. But when I use the equations to find one of the other unknown variables everything cancels out and I get zero. There is an example in the book, but it gives the height the fish is dropped from. I feel like I need to know another variable in order to solve this.
