     It's an amazing change when a caterpillar (毛毛虫) turns into a butterfly. That just might explain Taiwan

singer Jolin Tsai's choice of name for her latest album (唱片／专辑).

     On March 27, Tsai will release Flower Butterfly, her first album for Warner, the company she signed to

recently.

     The 28-year-old Tsai is known for the challenges she takes on. This time it is ballet. For the video that

goes with the album, she had to pirouette (用脚尖旋转) 20 times without stopping. It was hard going. When

she started training she couldn't even manage to spin (旋转) three times.

     "It took me longer to learn the move than anything I've ever tried!"she said.

     If the ballet was hard, the photo for the album art may have been harder. Tsai had to hang upside down

from a wire for an hour. It was so that her shadow (影子) would seem like a butterfly spreading its wings.

     But Tsai is facing another challenge. Her old record company (唱片公司), EMI will release an album of

music Tsai recorded when she was with the label. This means that Flower Butterfly will be fighting it out in

the market with old Jolin music.

     But Tsai didn't seem to care about the problems with her old company:

      "I've trained myself to be strong. I hope that other girls will follow my example and be themselves. Don't

be afraid of what other people say. One day you'll turn into a beautiful butterfly."

一滑块经水平轨道AB，进入竖直平面内的四分之一圆弧轨道BC。已知滑块的质量m=0.60kg，在A点的速度v_A=8.0m/s，AB长x=5.0m，滑块与水平轨道间的动摩擦因数μ=0.15，圆弧轨道的半径R=2.0m，滑块离开C点后竖直上升h=0.20m，取g=10m/s²。求：

（1）滑块经过B点时速度的大小；

（2）滑块经过B点时圆弧轨道对它的支持力的 大小；

（3）滑块在圆弧轨道BC段克服摩擦力所做的功。
