题1.1：已知质点沿x 轴作直线运动，其运动方程为3322)s m 2()s m 6(m 2t t x --?-?+= 。求（l ）质点在运动开始后s 0.4内位移的大小；（2）质点在该时间内所通过的路程。 题1.1解：（1）质点在4.0 s 内位移的大小 m 3204-=-=?x x x （2）由 0)s m 6()s m 12(d d 232=?-?=--t t t x 得知质点的换向时刻为 ｓ2=P t （t = 0不合题意） 则：m 0.8021=-=?x x x m 40x 242-=-=?x x 所以，质点在4.0 s 时间间隔内的路程为 m 4821=?+?=x x s 题1.2：一质点沿x 轴方向作直线运动，其速度与时间的关系如图所示。设0=t 时，0=x 。试根据已知的图t v -，画出t a -图以及t x -图。 题1.2解：将曲线分为AB 、BC 、CD 三个过程，它们对应的加速度值分别为 2A B A B AB s m 20-?=--=t t v v a （匀加速直线运动） 0BC =a （匀速直线） 2C D C D CD s m 10-?-=--= t t v v a （匀减速直线运动） 根据上述结果即可作出质点的a －t 图 在匀变速直线运动中，有 2002 1at t v x x + += 间内，质点是作v = 201s m -?的匀速直线运动，其x －t 图是斜率k = 20的一段直线。 题1.3：如图所示，湖中有一小船。岸上有人用绳跨过定滑轮拉船靠岸。设滑轮距水面高度为h ，滑轮到原船位置的绳长为0l ，试求：当人以匀速v 拉绳，船运动的速度v '为多少？

Time is treated as if it were something almostreal. (People budget it, waste it, steal it, kill it, cut it, account for it;they also charge for it.) They do this because time is a precious resource. 3. Everyone is in a rush —often under pressure. City people always appear to be hurrying to get wherethey are going, restlessly seeking attention in a store or elbowing others asthey try to complete their shopping. 4. Don’t take it personally. This isbecause people value time highly and they resent someone else “wasting” it beyond a certain appropriatepoint. 5. New arrivals in America will miss opening exchanges,the ritual interaction that goes with a cup of coffee or tea and leisurelychats. 6. Americans produce a steady flow of labor-savingdevices. They communicate rapidly through faxes, phone calls or emails ratherthan through personal contacts. 7.

大学物理上册课后习题答案
习题解答 习题一 1-1 ｜r ?｜与r ? 有无不同?t d d r 和t d d r 有无不同? t d d v 和t d d v 有无不同?其不同在哪里?试举例说明． 解： （1）r ?是位移的模，?r 是位矢的模的增量， 即r ?1 2r r -=，1 2 r r r ? ?-=?； （2）t d d r 是速度的模，即t d d r = =v t s d d . t r d d 只是速度在径向上的分量. ∵有r r ?r =（式中r ?叫做单位矢），则t ?r ?t r t d d d d d d r r r += 式中t r d d 就是速度径向上的分量， ∴ t r t d d d d 与r 不同如题1-1图所示. 题 1-1图 (3) t d d v 表示加速度的模，即 t v a d d ? ?= ，t v d d 是加速度a 在切向上的分量.
∵有ττ??(v =v 表轨道节线方向单位矢），所以 t v t v t v d d d d d d τ τ???+= 式中dt dv 就是加速度的切向分量. ( t t r d ?d d ?d τ??Θ与的运算较复杂，超出教材规定，故不予 讨论) 1-2 设质点的运动方程为x =x (t )，y =y (t )，在计算质点的速度和加速度时，有人先求出r ＝ 2 2 y x +，然后根据v =t r d d ，及a ＝ 2 2d d t r 而求得结果； 又有人先计算速度和加速度的分量，再合成求得结果，即 v =2 2 d d d d ?? ? ??+??? ??t y t x 及a = 2 22222d d d d ??? ? ??+???? ??t y t x 你认为两种 方法哪一种正确？为什么？两者差别何在？ 解：后一种方法正确.因为速度与加速度都是矢量，在平面直角坐标系中，有 j y i x r ? ??+=， j t y i t x t r a j t y i t x t r v ??? ???? ?222222d d d d d d d d d d d d +==+==∴ 故它们的模即为 2 222 22222 2 2 2d d d d d d d d ? ?? ? ??+???? ??=+=? ? ? ??+??? ??=+=t y t x a a a t y t x v v v y x y x
