From Kotaku:


The questions asked if a blue angry bird conserves energy when it splits in three, or a white bird conserves momentum when it drops its bomb. One question had students ricochet an angry bird off of a block in the world and then determine the coefficient of restitution and the mass of the angry bird.

From WiredScience:


On Earth, the vertical acceleration should be -9.8 m/s2. I can use this to find the length of that sling shot as:
