# Science of Apps! - Part 1: Flappy Bird

Classical Mechanics Level 3

In the insanely addictive game, Flappy Bird, the player's objective is to get a bird through some pipes. Sounds simple, right?

Wrong. The bird is a odd one that only flaps it's wings when you touch your screen. This causes a small burst in speed sending it up, and then causing to plummet, requiring you too tap the screen again. This incessant screen-tapping is especially difficult when you get to the pipes, because maintaining a level height is feat which requires quite a lot of finesse.

Now, every time you tap the screen, the bird is launched up, and comes back down to its original height after just $$1$$ second. If the game obeys the laws of physics, and takes place on Earth, ($$g=9.8 \text{ m/s}^2$$), and the small bird has a mass of about $$500$$ grams, find the momentum of the bird right after you touch the screen.

This problem is part of the Science of Apps! series
