Dear Kate,
I am writing to you in English. I hope you can understand it.
I love studying in London and      1     . Most of them are my classmates. From Monday to Friday, we have Chinese, math, physics and P.E. in the morning. I like Chinese and physics,       2       . I don’t like math. It’s too boring. At noon, I have to have lunch at school         3        . We usually have two classes in the afternoon, art and politics. We finish our classes at 3:30 p.m. After school, my friends and I always play soccer on the playground. And then we go home by bus.
On weekends,        4        . We often go to the park and sometimes we go to the movies in the evening.         5         . I like some famous stars like Jackie Chan.
Oh, I have no time to write more. Please write back soon.
Best wishes,
Wang Gang

如图所示,在竖直平面内有—个半径为R且光滑的四分之一圆弧轨道AB,轨道上端A与一光滑竖直轨道相切,轨道下端B与水平轨道BCD相切,BC部分光滑且长度大于R,C点右边轨道粗糙程度相同且足够长.现有长也为R的轻杆,轻杆两端固定两个质量均为m的完全相同的小球a、b(可视为质点).用某装置控制住上面的小球a,使轻杆竖直且下面的小球b与A点等高,然后由静止释放,杆将沿轨道下滑.设小球始终与轨道接触,重力加速度为g

小题1:求小球b到达C点时的速度大小.

小题2:若小球b过C点后,滑行s距离后停下,而且s>R.试求小球与粗糙平面间的动摩擦因数.
