二、完形填空。
Some people say they have a solution to the problems of car crowding and pollution. In many cities, hundreds of people 1 bikes to work every day. In the New York City, some bike riders have even founded a group: Bike for a Better City. They say if more people ride bikes to work, there would be 2 cars and less dirty air.
For several years this group has tried to gather help for bike riders. They want to have special roads 3 bikes only, because when bikes and cars use the same roads, there may be accidents. Bike for a Better City thinks if there were bike roads, more people would use bikes.
But no bike roads have been established 4 . Not everyone thinks it is a good 5 . Drivers don’t like it, and some shop owners don’t like it, 6 . And most people live 7 far from the city to travel by bike. Still, 8 has been done about it. On Saturdays and Sundays, the largest open park in New York is 9 to cars, and the roads may be used by bikes only, but the group still says this is not enough and goes on fighting 10 bike roads. I think there will be more bike roads in the future.

得vB=0.4m/s
16．（2025·亭湖模拟）某兴趣小组研究弹簧振子，设计了如图所示的装置，一个轻弹簧竖直放置，一端固定于地面，另一端与质量为m的物体B固连在一起，整个装置被一个口径略大且足够长的光滑圆套约束（图中未画出），现将质量也为m的物体A由B的正上方某一高度处自由释放，A和B发生碰撞后两者一起以相同的速度向下运动（但不粘连），AB在以后的振动过程中恰好不会分离，弹簧的劲度系数为k，整个振动过程弹簧处于弹性限度内，忽略A、B的体积，不计空气阻力，m、k、g为已知量，求：
（1）AB一起振动过程中最大加速度的大小；
（2）小组中的甲同学通过研究弹簧弹力做功，得出了弹簧的弹性势能表达式（x为弹簧形变量），求A释放前距B的高度；
（3）已知AB一起振动的周期为T，以A与B碰撞为计时起点，求AB振动到最高点的时刻。
【答案】（1）解：AB在以后的振动过程中恰好不会分离，所以振动最高点为弹簧原长位置，此时加速度最大．有
解得
