P2_3 Killing Two Birds with One Stone

Abstract

The famous idiom ‘to kill two birds with one stone’ is often used throughout everyday life to describe achieving two things with only one action. We are considering the physical scenario in which this phrase could be possible. We found that a stone thrown at a velocity of 18.95 ms-1 and 54.7◦ to the horizontal would kill a hummingbird, and from here found that the falling stone would kill a second hummingbird positioned 5.33 m away at an angle of 15.23◦ SE with respect to the first bird.
