2.There’s a chest of drawers in the room, and you want to push it out of the way. What is the best way to do it? Take all things into consideration. For example, where to push, the friction, what’s possibly inside, etc.
说你有一个五斗橱,你希望推开它.什么是推开它的最佳方式?要求考虑所有因素,比如说,推五斗橱的那个地方,摩擦力,还有五斗橱里的东西等等.
请大家帮忙说一下思路就好.因为是考虑所有因素,所以只要有理即可.
我真的很惧做这种看似简单实则不简单的实践题~

推动它只需考虑摩擦力(空气阻力还要考虑的话我就无语了)设为F还须知道该地的平均摩擦系数U F=MGU 出这么大力就行了
