【解析】升降机先做加速运动,后做匀速运动,最后做减速运动,在加速阶段,所需时间 ,通过的位移为,在减速阶段与加速阶段相同,在匀速阶段所需时间为：,总时间为：,故C正确,A、B、D错误；故选C。 【点睛】升降机先做加速运动,后做匀速运动,最后做减速运动,根据速度位移公式和速度时间公式求得总时间。 3．（多选）甲、乙两汽车同一条平直公路上同向运动,其速度—时间图像分别如图中甲、乙两条曲线所示。已知两车在t2时刻并排行驶,下列说法正确的是（） A. 两车在t1时刻也并排行驶 B. t1时刻甲车在后,乙车在前 C. 甲车的加速度大小先增大后减小 D. 乙车的加速度大小先减小后增大 【来源】2018年普通高等学校招生全国统一考试物理（全国II卷） 【答案】 BD 点睛：本题考查了对图像的理解及利用图像解题的能力问题

4．（多选）地下矿井中的矿石装在矿车中,用电机通过竖井运送至地面。某竖井中矿车提升的速度大小v随时间t的变化关系如图所示,其中图线①②分别描述两次不同的提升过程,它们变速阶段加速度的大小都相同；两次提升的高度相同,提升的质量相等。不考虑摩擦阻力和空气阻力。对于第①次和第②次提升过程, A. 矿车上升所用的时间之比为4:5 B. 电机的最大牵引力之比为2:1 C. 电机输出的最大功率之比为2:1 D. 电机所做的功之比为4:5 【来源】2018年全国普通高等学校招生统一考试物理（全国III卷） 为2∶1,选项C正确；加速上升过程的加速度a1=,加速上升过程的牵引力F1=ma1+mg=m(+g),减速上升过程的加速度a2=-,减速上升过程的牵引力F2=ma2+mg=m(g -),匀速运动过程的牵引力F 3=mg。第次提升过程做功W1=F1××t0×v0+ F2××t0×v0=mg v0t0；第次提升过 程做功W2=F1××t0×v0+ F3×v0×3t0/2+ F2××t0×v0 =mg v0t0；两次做功相同,选项D错误。
