6、[黄冈八模·文海]2026届高三大练习(二)2英语答案

可知以H为纵轴,横轴应取;若系统的机械能守恒,则图线的斜率k应满足的关系式为k=。
(4)实验过程中,系统需要克服一定的空气阻力和摩擦力做功,设阻力恒为f,则有MgH-mgH-fH=(M+m)v2可得H=·,则有k实=>k理=,故B正确。
(5)实际上用挡光时间计算的速度是遮光条经过光电门时的平均速度,等于挡光过程中间时刻的速度,不是遮光条上沿到光电门中心时的速度(挡光过程的初速度),则有Mg(H-d)-mg(H-d)=(M+m)v2
可得H=·+d
可知图线不过原点的原因是:实验中未考虑遮光条宽度对实验的影响。
13.答案　(1)1 m/s　(2)40 N·s
解析　(1)喷气过程中,宇航员甲与喷出的气体整体动量守恒,则有0=Mv-mv0,
