在一次抗洪救灾工作中,一架直升机A用长H=50m的悬索(重力可忽略不计)系住一质量m=50kg的被困人员B,直升机A和被困人员Bv0=10m/s的速度一起沿水平方向匀速运动,如图甲所示。某时刻开始收悬索将人吊起,在5s时间内,AB之间的竖直距离以l=50-t2(单位:m)的规律变化,取g=10m/s2。求:

(1)求这段时间内悬索对被困人员B的拉力大小。

(2)求在5s末被困人员B的速度大小及位移大小。

(3)直升机在t=5s时停止收悬索,但发现仍然未脱离洪水围困区,为将被困人员B尽快运送到安全处,飞机在空中旋转后静止在空中寻找最近的安全目标,致使被困人员B在空中做圆周运动,如图乙所示.此时悬索与竖直方向成37°角,不计空气阻力,求被困人员B做圆周运动的线速度以及悬索对被困人员B的拉力。(sin 37°=0.6,cos 37°=0.8)

                                                                       Gift Giving 
     1._____
     There are many occasions (场合) for giving gifts in modern industrialized societies; birthdays, naming
ceremonies, weddings, anniversaries, New Year, It is common to give gifts on many of these celebrations
in western cultures. In addition, special events, such as one' s first day of school or graduation from university,
often require gift fiving. 
     2._____ 
     What is happening when we give gifts? Most important, we are exchanging gifts. If someone gives me a
gift for my birthday, I know that I am usually expected to give one on his or her next birthday. A gift builds
up or confirms a social obligation (义务). 
     3._____ 
     Gifts tighten personal relationships and provide a means of communication between loved ones. People say
that a gift lets the recipient (接受者) know we are thinking of them, and that we want to make the person "feel
special." We want people to feel wanted, to feel part of our social or family group. We give presents to say "I'm
sorry." Sometimes it is difficult for us to find a present that someone will like. Sometimes we give things that
we like or would frrl comfortable with. In all these cases, the gifts are sending out messages-often very
expressive ones. 
     4._____
     People tend to talk about presents in a fairly loving way. A woman whose mother had died years ago
described the many gifts around her house. These were gifts that her mother had given her over the years:"I
appreciate these, and they mean something to me," the woman said, "because I remember the occasions they
were given on, and that they were from my mother, and the relationship we've had." The gifts remain and keep
the relationship alive in mind. This woman felt the same way about the gifts she gave to others. She hoped that
the recipients would look at here gifts in years to come and remember her.
     5._____ 
     Emotions (情感) like these suggest that a positive spirit still lies behind gift giving. They prove that the
anthropologist Claude Levi-Strauss was wrong to say that modern western gift giving is highly wasteful. Studies
in Canada and elsewhere have also shown that this is not the case. Each gift is unique even if so many are given.
The emotional benefit for those who exchange gifts is the very reason for the tradition to continue.
