1、- 1 -广东省普宁市华美实验学校 2018-2019 学年高一物理上学期期末考试试题(扫描版)- 2 - 3 - 4 - 5 -华美高一物理期末考试参考答案:1 2 3 4 5 6 7 8 9 10 11 12 13 14B B A B C D D B ACD BC AC AC CD AB15【答案】(1)相同 (2)远小于 (3)等于16【答案】(1)AC (2)4.0017.【答案】 (1)5 N (2)10 N (3)10 N解:地面上, FN mg,则滑动摩擦力(即最大静摩擦力 Fmax)大小为Fmax F N mg 0.5210 N10 N.(1)当 F5 N 时, FFmax,物

2、体滑动则地面对物体的滑动摩擦力的大小 F 滑 F N mg 10N.(3)物体运动过程中突然把推力去掉,地面对物体的摩擦力为滑动摩擦力,其大小 F 滑 10 N.18【答案】(1)8 m/s 2 (2)48 m (3)64 m【解析】(1)由牛顿第二定律有: Ff ma 代入数据解得: a8 m/s 2(2)由匀变速直线运动公式: x vt at2 加速度方向与速度方向相反,代入数据得 x48 m.(3)由计算得刹车后的加速度知汽车经 t 4 s 即停下所以 6 s 内位移与 4 s 内位移相等即由公式: x vt at2 以 t4 s 代入得: x64 m.19【答案】(1)9 m/s (2

3、)1.8 m/s,方向向左 (3)19.60 m【解析】(1)对木块和木板组成的系统,有: 1(m M)g( m M)a1v v 2 a1x0, x0 x L,代入数据得: v19 m/s(2)由牛顿第二定律可知: am 2g9 m/s 2aM m/s26 m/s 2m 运动至停止时间为: t1 s1 s此时 M 速度: vM v1 aMt19 m/s61 m/s3 m/s,方向向左,- 6 -此后至 m、 M 共速时间为 t2,有: vM aMt2 amt2得: t20.2 s 共同速度 v 共 1.8 m/s,方向向左(3)至共速 M 位移: x1 (t1 t2) 1.2 m6.48 m共速后 m、 M 以 a1 1g1 m/s 2向左减速至停下位移:v 2 a1x2 x21.62 m 最终 AP 间距: x11.5 m x1 x219.60 m.
