如果鸟儿会奥数,那么全世界的航空公司都会撒花庆祝。因为让他们无比头疼的飞鸟撞机事件有望得到彻底解决。飞机驾驶员再也用不着提心吊胆,生怕遭遇“鸟炮弹”的突然袭击;每年有数以千计的鸟儿可以逃脱被坚固的飞机机身撞晕,被卷进发动机绞碎的可旧噩运。什么?你不信?那就先来做一道经典的奥数题。什么?你没学过奥数?不要紧,这道题只能算奥数题里的小儿科,不上奥数班也能算个八九不离十。假设一架飞机和一只鸟从相距1000米的两地同时出发,相向而行。飞机的速度是300米/秒,鸟的速度是10米/秒。请问,它们多久会撞到一起?给你5分钟时间计算……好,时间到!答案就是3秒多一点点。请问,你对这个结果有何感想?是不是觉得时间
If the number of birds will be Austrian, then the world’s airlines will sprinkle flowers to celebrate. Because they are very headache flying bird collision is expected to be completely resolved. Aircraft pilots no longer need to be afraid of fear of encountering a sudden attack on “bird shells.” Each year thousands of birds escape the stun of the solid airplane fuselage, the old bad luck of being entangled in the engine . What? You do not believe? Then first to do a classic Mathematical Olympiad. What? You have never learned Mathematical Olympiad? It does not matter, this question can only be counted in the Mathematical Olympiad question Pediatrics, not on the Mathematical Olympiad can count as one hundred and fate. Suppose an airplane and a bird are traveling at the same time from two places 1000 meters apart. The speed of the plane is 300 m / s, the speed of the bird is 10 m / s. Excuse me, how long will they collide? Give you 5 minutes to calculate ... Well, time is up! The answer is a little more than 3 seconds. Excuse me, how do you feel about this result?
