经听证会和报市政府同意，广州市物价局公布了《广州自来水价格改革方案》。从2006年元旦起，广州市民用水和工业用水价格都有所提高，综合水价达到每立方米1.69元。有关部门还决定待条件成熟后在广州实行阶梯式计量水价，好按月水量多少缴费，用水越多，水价越高。

辨题：水价是政府根据需要任意规定的。

如图所示，质量分别为m和M的滑块A和B静止于光滑的水平台面上，A和B之间夹有一轻质弹簧（A、B与弹簧不连接），弹簧处于被压缩状态，有一轻质绳连接着A和B。水平台面左端连接着一半径为R=0.2m的光滑圆轨道PQ，右端为一倾角为37°的足够长的斜面CD，滑块B与斜面CD间的动摩擦因数为。烧断两滑块间的轻质绳后，由于弹簧弹力的作用，滑块A将沿圆轨道做圆周运动，且在最高点P轨道对滑块的压力恰好等于滑块的重力。已知两滑块的质量之比为，重力加速度g=10m/s².求：

（1）烧断细绳，弹簧恢复原长时两滑块的速度大小；

（2）滑块B将沿斜面上滑，且从斜面底端C开始经过t=0.5s，恰好经过D点，求CD的长度。

B.广州地区

C.客家地区

D.佛山地区
