肯尼迪被刺杀的具体日期要求写出年月日.

John Kennedy
On November 22,1963,when he was hardly past his first thousand days in office,John Fitzgerald Kennedy was killed by an assassin's bullets as his motorcade wound through Dallas,Texas.Kennedy was the youngest man elected President; he was the youngest to die.
Of Irish descent,he was born in Brookline,Massachusetts,on May 29,1917.Graduating from Harvard in 1940,he entered the Navy.In 1943,when his PT boat was rammed and sunk by a Japanese destroyer,Kennedy,despite grave injuries,led the survivors through perilous waters to safety.

Hello,the contents of my talk today is an excerpt from United States 35th President Kennedy served lecture Hi,it is known that Kennedy was a United States top ten cultural icons,and Presidents in nearly 50 years,Kennedy's top rated top.Excerpt from my talk today serve the great President's speech.完全一模一样翻译过来的.

没有付出,就没有收获；有付出,也不一定有收获.如果只懂得回报,却不懂得付出,最终谁都救不了你,美国照样救不了.
只有一起齐心协力,共同为了大家的目标去奋斗,才会各得其所.
大道至简,天下一理.

解题思路：（1）已知飞机的加速度、初速度、末速度，求解飞机运动时间，根据速度时间公式即可求解．
（2）根据位移速度公式列式即可求舰长．

（1）由速度和位移公式可得：
v²-v₀²=2ax
可得：v₀=10
15m/s；
（2）由匀变速直线运动规律可得，飞机的跑道长度至少需要的距离为：
s=
v2
2a=[2500/2×5]=250m；
答：（1）初速度为10
15m/s；；
（2）飞机的跑道至少需要250m．

点评：
本题考点： 匀变速直线运动规律的综合运用．

考点点评： 本题是匀变速直线运动的基本公式的直接应用，属于比较简单的题目，解题时要学会选择合适的公式，这样很多问题就会迎刃而解了．

（1）凡尔赛－华盛顿体系。美苏两极格局。杜鲁门主义的出台。
（2）在资本主义内部进行调整，加强国家对经济的干预和指导。
（3）欧盟。世界上最大的经济体。
（4）明治维新。成为仅次于美国的世界第二号资本主义经济大国。
（5）2001 年中国上海成功举办第九届亚太经济合作组织成员国领导人会议或者 2001 年中国加入世界贸易组织。
（6）重视教育；抓住机遇；发展科技；制定适当的经济发展政策等。

C O(∩_∩)O~满意请采纳,亲

不错,基本的意思都在了.
稍微改动一下：
Analysis of US economic assistance to Africa in Kennedy era
注：
1 shallow 就不需要了
2 US 专指美国,American 可能指美洲,这里专指美国,所以用 US

C

例如早晨4点从北京出发坐20个小时飞机到纽
说明到达纽约时是北京时间当天12点
纽约时间比北京早13个小时
此时的纽约时间是头一天下午1点
但是在夏时制时到达纽约时纽约的时间是下午2点

B

解题思路：已知飞机的加速度、位移、末速度，求解飞机的初速度，此题不涉及物体运动的时间，选用匀变速直线运动的位移时间公式便可解决．

设飞机的初速度为v₀，已知飞机的加速度a=4.5m/s²、位移x=100m、末速度v=50m/s，此题不涉及物体运动的时间，
则由匀变速直线运动的位移时间公式：v²-v₀²=2ax
解得：v₀=40m/s
故选：B

　　刺杀林肯的那个人——约翰·威尔克斯·布思,生于1838年.而杀害肯尼迪的凶手——李·哈维·奥斯瓦德,则出生于1938年之后.两人都是南方人,他们俩自己也都是尚未审判就被枪杀.约翰·威尔克斯·布恩和李·哈维·奥斯瓦尔德两人的名字都是由15个英文字母组成!
　　布思在剧院犯下罪行,逃入一座谷仓.奥斯瓦德是在一座仓库的窗口对准肯尼迪扣动扳机的,然后逃进一家剧院.
　　而且他们两人对自己的死亡都有着奇特的预感.
　　在被刺的那一天,林肯对他的卫兵威廉·H·克鲁克说：“我相信有人要谋杀我…….我毫不怀疑他们会动手…….如果发生这样的事,是无法阻止的.我没有任何办法.”
　　而肯尼迪毫不怀疑地对他的妻子杰姬（杰奎琳）以及他的私人顾问肯·奥唐纳尔说：“如果谁想从窗口用步枪向我射击,谁也无法防止,因此又何必多操心呢?”
　　他讲这话是在1963年11月22日.肯尼迪是在讲了这话几个小时之后被枪击中的.
　　林肯和肯尼迪两者都是历史上有名的民权运动者.两人都是在星期五被枪杀的,并都是被击中在头后部.两人的妻子都在场.
　　林肯是在福特大戏院遇刺的,肯尼迪则是在汽车上被刺的,汽车是福特汽车公司出品的,是林肯牌.
　　肯尼迪有一个名叫伊夫林·林肯的秘书,据报道,他曾劝告肯尼迪不要去达拉斯.林肯有一位私人秘书的名字与肯尼迪相同,都叫约翰·肯尼迪.

牛 百度上有,仔细地照

John F.Kennedy,U.S.President
Born:29 May 1917
Birthplace:Brookline,Massachusetts
Died:22 November 1963 (assassination by gunshot)
Best Known As:President of the United States,1961-63
John F.Kennedy's 1963 assassination was one of the most shocking public events of the 20th century.Kennedy served in the U.S.Navy during World War II,commanding the patrol boat PT-109 and leading his crew to rescue after the boat was sunk by the Japanese in the Solomon Islands.A Democrat,"JFK" was elected to the U.S.House of Representatives from Massachusetts' 11th district in 1946.In 1952 he moved up to the U.S.Senate,defeating Henry Cabot Lodge.He married Jacqueline Bouvier on 12 September 1953; they had two children,Caroline (b.1957) and John Jr.(b.1960).(A third child,Patrick,was born on 7 August 1963 and died two days later.) JFK was elected to replace President Dwight Eisenhower in 1960 (narrowly defeating Eisenhower's vice-president,Richard Nixon); he swept into office with a reputation for youthful charm,impatience,wit and vigor.Kennedy's term was sometimes called the New Frontier,a phrase he coined in his acceptance speech at the 1960 Democratic convention.Kennedy was shot to death by sniper Lee Harvey Oswald during an open-car motorcade in Dallas,Texas on 22 November 1963; two days later,Harvey was shot and killed by another man,Jack Ruby.Kennedy was succeeded by Lyndon Johnson.
Kennedy was sometimes called by his nickname,Jack...U.S.senators Ted Kennedy and the late Robert F.Kennedy are Kennedy's younger brothers...His son John Kennedy Jr.died in a 1999 private plane crash...His older brother Joe Kennedy Jr.and his sister Kathleen were also killed in plane crashes during the 1940s...His father Joseph Kennedy was a controversial businessman and former ambassador to Great Britain...Kennedy's maternal grandfather,John "Honey Fitz" Fitzgerald,was mayor of Boston...Kennedy suffered from back trouble for most of his adult life; the stiff-backed rocking chair he sometimes used in the Oval Office became a personal symbol...While recovering from two serious back operations he wrote Profiles in Courage,which won the 1957 Pulitzer Prize for biography...He also suffered from the glandular disorder Addison's Disease...Richard Nixon's running mate in 1960 was Henry Cabot Lodge,whom Kennedy defeated for senator in 1952...Kennedy attended the private school Choate and graduated from Harvard College in 1940...Kennedy was America's first Catholic president.

I am all good detective Mr.Mao Li.A lot of case history in my hands one by one to resolve,for example,why the Titanic sank,I know; for example,why John F.Kennedy was assassinated,I know.But not enough fun,this time I'll look into the case years ago,Snow White was killed on the case.Many people think that it is Snow White,she was killed the letters I do not think so.Let us remind ourselves of the scene at that time.
First of all,we interviewed about the Queen.
Are there people in the world will be jealous of your good looks?We re-interviewed about Snow White.
As we all know is called the motive to kill.Of course,we have the story of seven very important role,and that is the Seven Dwarfs,ask them!
The story takes place in a bright morning,Snow White and the Seven Dwarfs in the park happy to take a walk.Queen's coming.
Stop-stop!Please note that the Apple,which is the world's most poisonous apple,is better than any poison,but the case was whether or not the case.After careful investigation,we are very fortunate that Apple has found that of future generations.Change the time,the gene mutation that future generations of Apple's become very tall,please Apple.
And the apple of our generations have had a lengthy exchange,finally found another suspicious case,it appears that we have to re-examine the history,maybe there will be another face.
It seems we need to re-examine the case and a bright morning,in the end what happened?It was a moment of history forever fixed,the letters was a vicious stepmother,killed his daughter,we were pushed down the cliff.This is another interpretation of history.
We are also the cause of death of the snow survey conducted by mobile users send text messages to 10,086,Unicom users to send text messages to 12,345,678,we have been following the six causes of death.
First,some quarters have not the water heater,she had to Xilengshuizao,first two,she had frozen to death.
Second,some quarters have water heaters,water Tai Tang,she was a Tangsi.
Third,the snow-trichloro Aihe milk,with the passage of time,a failure.
Fourth,do the exercise over and over again,the Fan Si Fan Si of the Fan Si,she was the Fan Si.
Fifth,heard about the story you a passive attitude,so perhaps she was dead.
When I looked at the bodies on the floor,I suddenly thought of the sixth cause of death,because her bedroom as long positions,the exhausted

根据美国一家最权威的杂志调查＜具体是哪本杂志我忘了请谅解＞
最受美国人欢迎的总统
第一位：林肯
第二位：华盛顿
第三位：罗斯福
而大多数美国人竟然连克林顿是谁都不知道～
真够郁闷的～

弹射系统对飞机提供的加速度是300m/s平方.而飞机离开弹射系统瞬间的速度需要知道肯尼迪航母的飞行甲板的具体长度.
