如图所示,水平支持面上静止叠放长方体物块A和B,A的长度为L=2m、高度h=0.8m,B的大小可以忽略,并置于A的左端.在距离A的右端一定距离(用S表示)的地方固定另一个长方体物体C,它的高度为A高的四分之三、长度为A长的五分之一.现对A作用一个水平恒力F,使A、B一起向C运动.已知A、B之间的最大静摩擦力为fm=25N,A、B以及A与地面间的动摩擦因数均为μ=0.4,A、B的质量分别为mA=10kg、mB=5kg.如果A在运动过程中与C发生碰撞,它将在碰撞后立即停止运动.

(1)为了保证B物体能在A、C发生碰撞后离开A的上表面,应使A、C之间的距离S至少多大?

(2)现使S等于(1)中所求值的两倍,为了保证B物体在A碰到C后能够不碰到C而直接落于水平支持面,求恒力F的最短作用时间;

(3)在S等于(1)中所求值两倍的条件下,计算B物体平抛运动中水平支持面上落点离A右端距离的范围.

One of the. earliest (11) in the Western world to formulate principles of health care based upon rational thought and (12) of supernatural phenomena is found in the work of the Greek physician Hippocrates. The writing (13) to him has provided a number of principles underiying modern medical practice. One of his most famous (14) , the Hippocratic Oath, is the foundation of contemporary medical ethics.

Hippocrates also argued that medical knowledge should be derived from a (15) of the natural science and the logic of cause and effect relationships. In this (16) thesis, On Air, Water, and Places, Hippocrates pointed out that human well-being is (17) by the totality of environmental (18) : living habits or lifestyle, climate, geography of the land, and the quality of air, and food.
