2007年10月24日，中国首颗探月卫星“嫦娥一号”在西昌卫星发射中心发射升空，准确进入预定轨道．随后，“嫦娥一号”经过变轨和制动成功进入环月轨道．如图所示，阴影部分表示月球，设想飞船在距月球表面高度为3R的圆形轨道Ⅰ上作匀速圆周运动，到达A点时经过暂短的点火变速，进入椭圆轨道Ⅱ，在到达轨道Ⅱ近月点B点时再次点火变速，进入近月圆形轨道Ⅲ，而后飞船在轨道Ⅲ上绕月球作匀速圆周运动．已知月球半径为R，月球表面的重力加速度为g₀，引力常量为G．不考虑其它星体对飞船的影响，求：

（1）飞船在轨道Ⅰ、Ⅲ的速度之比．

（2）飞船在轨道Ⅰ上的运动周期．

（3）飞船从轨道Ⅱ上远月点A运动至近月点B所用的时间．

Next time a customer comes to your office, offer him a cup of coffee. And when you’re doing your holiday shopping online, make sure you’re holding a large glass of iced tea. The physical sensation of warmth encourages emotional warmth, while a cold drink in hand prevents you from making unwise decisions-those are the practical lesson being drawn from recent research by psychologist John A. Bargh.

Psychologists have known that one person’ s perception of another’ s "warmth" is a powerful determiner in social relationships. Judging someone to be either "warm" or "cold" is a primary consideration, even trumping evidence that a "cold" person may be more capable. Much of this is rooted in very early childhood experiences, Bargh argues, when babies’ conceptual sense of the world around them is shaped by physical sensations, particularly warmth and coldness. Classic studies by Harry Harlow, published in 1958, showed monkeys preferred to stay close to a cloth "mother" rather than one made of wire, even when the wire "mother" carried a food bottle. Harlow’ s work and later studies have led psychologists to stress the need for warm physical contact from caregivers to help young children grow into healthy adults with normal social skills.

Feelings of "warmth" and "coldness" in social judgments appear to be universal. Although no worldwide study has been done, Bargh says that describing people as "warm" or "cold" is common to many cultures, and studies have found those perceptions influence judgment in dozens of countries.

To test the relationship between physical and psychological warmth, Bargh conducted an experiment which involved 41 college students. A research assistant who was unaware of the study’s hypotheses, handed the students either a hot cup of coffee, or a cold drink, to hold while the researcher filled out a short information form: The drink was then handed back. After that, the students were asked to rate the personality of "Person A" based on a particular description. Those who had briefly held the warm drink regarded Person A as warmer than those who had held the iced drink.

"We are grounded in our physical experiences even when we think abstractly." says Bargh.
