解“追及问题”的一般步骤是:(1)分析二者的运动规律,分别写出它们的运动位移表达式;(2)根据二者同时到达同一位置,列出位移关系方程;(3)解方程,并根据时间t的物理意义作出相应的结论.
The general steps for solving the “chasing problem” are: (1) Analyze the motion laws of the two and write their motion displacement expressions respectively; (2) List the displacement relationship equations based on the two simultaneously reaching the same position; (3) Solve equations and make corresponding conclusions based on the physical meaning of time t.
