今日份解锁:“加拿大滑铁卢公牛物理思维挑战赛”!!!
滑铁卢牛顿物理思维挑战赛(SIN)于1969年由滑铁卢大学物理系发起,旨在激发高中生对物理的兴趣。加拿大滑铁卢大学成立于1957年,是一所研究型公立大学,位于安大略省西南部城市滑铁卢,以注重学习和实践的合作教育而闻名。2011年至2013年,学校一直被Maclean杂志评为加拿大综合大学排名前三名,是北美最好的大学之一。每年,来自加拿大300所高中的近2500名学生参加SIN比赛。近年来,在加拿大境外参加SIN的学生人数显著增长,国际影响力逐步提升。题目新颖,结合时事,既有趣又具有挑战性。

Romeo sets off in his spaceship to marry Juliet, who lives on the planet Lovelon, 10 light-years away from earth. He can accelerate at 15 m/s2, and must decelerate at the same rate, in order to stop at Lovelon. Unknown to him, Juliet has taken an earlier shuttle back to Earth and she will wait there. Since there is no communication, Romeo will have to travel back again! Romeo left yesterday, on April 30, 1997. What is the earliest year in which they can be wed? Romeo and Juliet are both classical persons, and they ignore any relativistic effects! 1 light-year is about 9.46 x 1015 m.

Romeo is landing back on Earth to claim his bride, Juliet. His spaceship is descending vertically at 50 m/s and he is 500m up when he throws a bouquet of Lovelon flowers horizontally (from his point of view) out of his ship to land near Juliet, who is waiting at the dockport, 40 m from his landing spot. How fast must Romeo throw his flowers in m/s so that they land at Juliet's feet? (Lovelon flowers are very slippery, and do not experience air resistance. They can also absorb quite a shock on landing and still look fresh!).
