(1)设第一次经过圆弧最低点C时速度大小为v,根据机械能守恒定律有:

1
2
mv2=mgR…①

设设第一次经过圆弧最低点C时受到的支持力大小为F,则:F?mg=m

v2
R
…②

联立①②两式得:F=1500N

(2)设从A到D过程中BC段摩擦力做功为W,由动能定理得:mg(h?R)+W=0?

m
v20

代入数据解得:W=-125J

设运动员在D点相对A点具有重力势能为EP,则有:Ep=mg(R-h)=50×10×(3-2)=500J?

EP>|W|

能从D点返回到A点.

(3)由题知,运动员从D点上升到最高点所经历的时间t=0.6s.设t时间内上升的高度为H,则H=

gt2

根据功能关系,蹬地增加的动能转化为上升H高度增加的重力势能,即:EK=mgH

代入数据解得:Ek=900J.

答:(1)运动员第一次经过圆弧最低点C时受到的支持力大小为1500N;

(2)能从D点返回到A点.

(3)其在BC段需通过蹬地增加900J的动能.

Xinjiangwan town SMP skate park is Shanghai's first skate park, at the same time, it is the world's largest best one. Its size is larger than American X-game park. The park is not only has 4500m beginners training field, and has intermediate venues and competitive sites and other different area. Xinjiangwan town SMP skateboard park has three division: namely blocks, bowl and half pipe. Each step has a different difficulty, the half pipe which is 42 meters long, 6 meters in height is most magnificient in the world. At the same time, the tunnel which set between the two bowl is also undisputed To become the world of print.玩滑板的给你翻译,哥们儿你要好好学英语啊,一般板仔的英语都很流利的
