1.3 动量守恒定律 练习题(解析版)
第一章动量守恒定律1.3 动量守恒定律一、单选题：1.如图所示，甲木块的质量为m1，以v的速度沿光滑水平地面向前运动，正前方有一静止的、质量为m2的乙木块，乙上连有一轻质弹簧．甲木块与弹簧接触后()A．甲木块的动量守恒B．乙木块的动量守恒C．甲、乙两木块所组成系统的动量守恒D．甲、乙两木块所组成系统的动能守恒解析：根据动量守恒定律的条件，以甲、乙为一系统，系统的动量守恒，A、B错误，C正确；甲、乙的一部分动能转化为弹簧的弹性势能，甲、乙系统的动能不守恒，D错误．答案：C2.2019年1月11日，我国在西昌卫星发射中心用“长征三号乙”运载火箭成功将中星2D卫星送入预定轨道．假设将发射火箭看成如下模型：静止的实验火箭，总质量M＝2 100 g，当它以对地速度v0＝840 m/s喷出质量Δm＝100 g的高温气体后，火箭的速度为(喷出气体过程中重力和空气阻力可忽略)()A．42 m/s B．－42 m/sC．40 m/s D．－40 m/s答案：B解析：[取火箭及气体为系统，设火箭的速度为v，则系统在向外喷气过程中满足动量守恒定律，取v0方向为正方向，由动量守恒定律得0＝Δmv0＋(M－Δm)v，解得v＝－Δmv0M－Δm＝－42 m/s，选项B正确．]3.如图所示，A、B两个小球在光滑水平面上沿同一直线相向运动，它们的动量大小分别为p1和p2，碰撞后A球继续向右运动，动量大小为p1′，此时B球的动量大小为p2′，则下列等式成立的是()A ．p 1＋p 2＝p 1′＋p 2′B ．p 1－p 2＝p 1′－p 2′C ．p 1′－p 1＝p 2′＋p 2D ．－p 1′＋p 1＝p 2′＋p 2答案：D解析：[因水平面光滑，所以A 、B 两球组成的系统在水平方向上动量守恒．取向右为正方向，由于p 1、p 2、p 1′、p 2′均表示动量的大小，所以碰前的动量为p 1－p 2，碰后的动量为p 1′＋p 2′，由系统动量守恒知p 1－p 2＝p 1′＋p 2′，经变形得－p 1′＋p 1＝p 2′＋p 2，D 对．]4.甲、乙两人站在光滑的水平冰面上，他们的质量都是M ，甲手持一个质量为m 的球，现甲把球以对地为v 的速度传给乙，乙接球后又以对地为2v 的速度把球传回甲，甲接到球后，甲、乙两人的速度大小之比为(忽略空气阻力) ( )A.2M M －mB.M ＋m MC.2(M ＋m )3MD.M M ＋m答案：D解析：[甲、乙之间传递球的过程中，不必考虑过程中的细节，只考虑初状态和末状态的情况．研究对象是由甲、乙二人和球组成的系统，开始时的总动量为零，在任意时刻系统的总动量都为零．设甲的速度大小为v 甲，乙的速度大小为v 乙，二者方向相反，根据动量守恒得(M ＋m )v 甲－Mv 乙＝0，则v 甲v 乙＝M M ＋m，选项D 正确．] 5.光滑水平桌面上有P 、Q 两个物块，Q 的质量是P 的n 倍．将一轻弹簧置于P 、Q 之间，用外力缓慢压P 、Q .撤去外力后，P 、Q 开始运动，P 和Q 的动量大小的比值为( )A ．n 2B ．n C.1nD ．1 答案：D解析：[撤去外力后，系统所受外力之和为0，所以总动量守恒，设P 的动量方向为正方向，则有p P－p Q＝0，故p P＝p Q，因此P和Q的动量大小的比值为1，选项D正确．]6.将一个光滑的半圆形槽置于光滑的水平面上，如图所示，槽左侧有一个固定在水平面上的物块．现让一个小球自左侧槽口A点正上方由静止开始落下，从A点落入槽内，则下列说法正确的是()A．小球在半圆槽内运动的过程中，机械能守恒B．小球在半圆槽内运动的全过程中，小球与半圆槽组成的系统动量守恒C．小球在半圆槽内由B点向C点运动的过程中，小球与半圆槽组成的系统动量守恒D．小球从C点离开半圆槽后，一定还会从C点落回半圆槽答案：D解析：[小球在半圆槽内运动，由B到C的过程中，除重力做功外，槽的支持力也对小球做功，小球机械能不守恒，由此可知，小球在半圆槽内运动的全过程中，小球的机械能不守恒，A错误；小球在槽内由A到B的过程中，左侧物块对槽有作用力，小球与槽组成的系统动量不守恒，由B到C的过程中，小球有向心加速度，竖直方向的合力不为零，系统的动量也不守恒，B、C错误；小球离开C点以后，既有竖直向上的分速度，又有水平分速度，小球做斜上抛运动，水平方向做匀速直线运动，水平分速度与半圆槽的速度相同，所以小球一定还会从C点落回半圆槽，D正确．]7.如图所示，质量为m＝0.5 kg的小球在距离车底部一定高度处以初速度v0＝15 m/s向左平抛，落在以v＝7.5 m/s的速度沿光滑水平面向右匀速行驶的小车中，小车足够长，质量为M＝4 kg，g取10 m/s2，则当小球与小车相对静止时，小车的速度大小是()A．4 m/s B．5 m/sC．8.5 m/s D．9.5 m/s答案：B解析：[小球和小车在水平方向上动量守恒，取向右为正方向，有Mv－mv0＝(M＋m)v′，解得v′＝5 m/s.]8.如图所示，轻弹簧的一端固定在竖直挡板上，一质量为m的光滑弧形槽静止放在光滑水平面上，弧形槽底端与水平面相切，一质量也为m的小物块从槽上高h处开始下滑，下列说法正确的是()A．在下滑过程中，物块和槽组成的系统机械能守恒B．在下滑过程中，物块和槽组成的系统动量守恒C．在压缩弹簧的过程中，物块和弹簧组成的系统动量守恒D．被弹簧反弹后，物块能回到槽上高h处答案：A解析：[对物块和槽组成的系统，在下滑过程中没有机械能损失，系统的机械能守恒，A正确；在下滑的过程中，物块在竖直方向有加速度，物块和槽组成的系统所受合外力不为零，不符合动量守恒的条件，故系统的动量不守恒，但系统在水平方向上动量守恒，B错误；在压缩弹簧的过程中，对于物块和弹簧组成的系统，由于挡板对弹簧有向左的弹力，所以系统受到的合外力不为零，则系统动量不守恒，C错误；因为物块与槽在水平方向上动量守恒，且两者质量相等，根据动量守恒定律知物块离开槽时物块与槽的速度大小相等、方向相反，物块被弹簧反弹后，与槽的速度相同，即两者做速度相同的匀速直线运动，所以物块不会再滑上弧形槽，D错误．]9．如图所示，一个木箱原来静止在光滑水平面上，木箱内粗糙的底板上放着一个小木块．木箱和小木块都具有一定的质量．现使木箱获得一个向右的初速度v0，则()A．小木块和木箱最终都将静止B．小木块最终将相对木箱静止，二者一起向右运动C．小木块在木箱内壁将始终来回往复碰撞，而木箱一直向右运动D．如果小木块与木箱的左壁碰撞后相对木箱静止，则二者将一起向左运动答案：B解析：[最终，木箱和小木块都具有向右的动量，并且相互作用的过程中总动量守恒，选项A、D错误；由于小木块与底板间存在摩擦，小木块最终将相对木箱静止，选项B正确，选项C错误．]二、多选题：10.关于动量守恒的条件，下面说法正确的是()A．只要系统内有摩擦力，动量就不可能守恒B．只要系统所受合外力为零，系统动量就守恒C．系统加速度为零，系统动量一定守恒D．只要系统所受合外力不为零，则系统在任何方向上动量都不可能守恒答案：BC解析：[动量守恒的条件是系统所受合外力为零，与系统内有无摩擦力无关，选项A错误，B正确；系统加速度为零时，根据牛顿第二定律可得系统所受合外力为零，所以此时系统动量守恒，选项C正确；系统合外力不为零时，在某方向上合外力可能为零，此时在该方向上系统动量守恒，选项D错误．]11.下列四幅图所反映的物理过程中，动量守恒的是()答案：AC解析：[A图中子弹和木块组成的系统在水平方向上不受外力，竖直方向所受合力为零，该系统动量守恒；B图中在弹簧恢复原长的过程中，系统在水平方向上始终受墙的作用力，系统动量不守恒；C图中木球与铁球组成的系统所受合力为零，系统动量守恒；D图中木块下滑过程中，斜面体始终受到挡板的作用力，系统动量不守恒．]12.如图所示，木块A静置于光滑的水平面上，其曲面部分MN光滑、水平部分NP粗糙，现有一物体B自M点由静止释放，设NP足够长，则以下叙述正确的是()A．A、B最终以同一不为零的速度运动B．A、B最终速度均为零C．A物体先做加速运动，后做减速运动D．A物体先做加速运动，后做匀速运动答案：BC解析：[系统在水平方向不受外力，故系统在水平方向动量守恒，因系统初动量为零，A、B在任一时刻的水平方向动量之和也为零，因NP足够长，B最终与A速度相同，此速度为零，B选项正确，A物体由静止到运动、最终速度又为零，C选项正确．]13.如图所示，小车放在光滑的水平面上，将系着绳的小球拉开到一定的角度，然后同时放开小球和小车，那么在以后的过程中()A．小球向左摆动时，小车也向左运动，且系统水平方向动量守恒B．小球向左摆动时，小车向右运动，且系统水平方向动量守恒C．小球向左摆到最高点，小球的速度为零而小车的速度不为零D．在任意时刻，小球和小车在水平方向上的动量一定大小相等、方向相反答案：BD解析：[以小球和小车组成的系统为研究对象，在水平方向上不受力的作用，所以系统在水平方向上动量守恒，由于初始状态小车与小球均静止，所以小球与小车在水平方向上的动量要么都为零，要么大小相等、方向相反，选项A、C错误，选项B、D正确．]三、非选择题：14.一辆质量m1＝3.0×103 kg的小货车因故障停在车道上，后面一辆质量m2＝1.5×103 kg的轿车来不及刹车，直接撞入货车尾部失去动力．相撞后两车一起沿轿车运动方向滑行了s＝6.75 m停下．已知车轮与路面间的动摩擦因数μ＝0.6，求碰撞前轿车的速度大小．(重力加速度取g＝10 m/s2)[解析]两车一起运动时，由牛顿第二定律得a＝F fm1＋m2＝μg＝6 m/s2v＝2as＝9 m/s两车碰撞前后，由动量守恒定律(取轿车滑行方向为正方向)得m2v0＝(m1＋m2)vv0＝m1＋m2m2v＝27 m/s.[答案]27 m/s15.如图所示，甲车质量m1＝20 kg，车上有质量M＝50 kg的人，甲车(连同车上的人)以v＝3 m/s 的速度向右滑行，此时质量m2＝50 kg的乙车正以v0＝1.8 m/s的速度迎面滑来，为了避免两车相撞，当两车相距适当距离时，人从甲车跳到乙车上，求人跳出甲车的水平速度(相对地面)应当在什么范围以内才能避免两车相撞？不计地面和小车的摩擦，且乙车足够长．[解析]人跳到乙车上后，如果两车同向，甲车的速度小于或等于乙车的速度就可以避免两车相撞以人、甲车、乙车组成的系统为研究对象由水平方向动量守恒得：(m1＋M)v－m2v0＝(m1＋m2＋M)v′，解得v′＝1 m/s以人与甲车为一系统，人跳离甲车过程水平方向动量守恒，得：(m1＋M)v＝m1v′＋Mu解得u＝3.8 m/s因此，只要人跳离甲车的速度u≥3.8 m/s就可避免两车相撞．[答案]大于等于3.8 m/s16.如图所示，在光滑的水平杆上套有一个质量为m的滑环，滑环通过一根不可伸缩的轻绳悬挂着一个质量为M的物块(可视为质点)，绳长为L.将滑环固定时，给物块一个水平冲量，物块摆起后刚好碰到水平杆；若滑环不固定，仍给物块以同样的水平冲量，求物块摆起的最大高度．[解析] 滑环固定时，根据机械能守恒定律，有MgL ＝12Mv 20，解得v 0＝2gL 滑环不固定时，物块的初速度仍为v 0，在物块摆起至最大高度h 时，它们的速度都为v ，在此过程中物块和滑环组成的系统机械能守恒，水平方向动量守恒，则：Mv 0＝(m ＋M )v12Mv 20＝12(m ＋M )v 2＋Mgh 由以上各式，可得h ＝m m ＋ML . [答案]m m ＋M L。

《宏观经济学》课后练习题参考答案4
第四章货币与通货膨胀一、选择题二、名词解释1、M1与M2：都是美联储计算货币存量的指标，M1是指通货加活期存款、旅行支票和其它支票性存款，被称为狭义的货币；M2是指加货币市场基金余额、储蓄存款以及小额定期存款，被称为广义的货币。
M1具有完全的流动性，但没有利息。
M2有利息但不具有完全的流动性。
M1与经济关联性强，而M2与货币政策关联性强。
2、货币需求函数：（1）货币需求函数是为了分析货币需求量的决定因素及其变动规律而建立的一种函数关系。
通常将决定和影响货币需求的各种因素作为自变量，而将货币需求本身作为因变量。
（2）比较典型的货币需求函数有：①传统货币数量论的交易方程式：PV=MY，其中M为货币数量，V为货币流通速度，P为一般物价水平，Y为实际国民收入；②剑桥方程式：M= kPY，其中M为货币数量，k为以货币形式持有的国民收入的比例，P为一般物价水平，Y为实际国民收入；③凯恩斯的货币需求函数：L=L1（Y）+L2（i）。
其中由交易动机和预防动机而产生的货币需求用L1表示，是收入Y的递增函数，即L1=L1（Y）；投机性货币需求L2则与利率有关，是利率的递减函数，即L2=L2（i）；④弗里德曼的货币需求函数：M=f｛P，r b，r c，1/P·dP/dt，w，y，u｝，其中，M表示名义货币量，P表示价格水平，r b表示债券的预期收益率，r c表示股票的预期收益率，1/P·dP/dt表示物价的预期变动率，w表示人力财富与非人力财富的比率，y表示货币收入，u为其他随机因素。
3、数量方程式：数量方程式是用来表示交易量与货币之间的关系的方程。
它有以下表示形式：MV=PT式中，M为流通中的货币数量，V为货币的流通速度，P为一般物价水平，T为社会总交易额。
交易方程式直观地表示了流通中的货币数量与一般物价水平之间的关系。
如果用Y代表实际GDP，P是GDP平减指数，而PY是名义GDP，数量方程式变为MV=PY。
