如图所示,小车停放在光滑的水平面上,小车的质量为M= 8kg,在小车水平面A处放有质量为m=2kg的物块,AB段是粗糙的水平面,BC是一段光滑的圆弧,在B点处与AB相切,现给物块一个V0=5m/s的初速度,物块便沿AB滑行,并沿BC上升,然后又能返回,最后恰好回到A点处与小车保持相对静止,求:

①从物块开始滑动至返回A点整个过程中,小车与物块组成的系统损失的机械能为多少?

②物块沿BC弧上升相对AB平面的最大高度为多少?

Border Gateway Protocol(BGP) is inter-autonomous system (1) protocol. BGP is based on a routing method called path vector routing. Distance vector routing is not a good candidate for inter-autonomous system routing because there are occasions on which the route with the smallest (2)count is not the preferred route. For example, we may not want a packet through an autonomous system that is not secure even though it is shortest route. Also, distance vector routing is unstable due to the fact that the routers announce only the number of hop counts to the destination without defining the path that leads to that(3)A router that receives a distance vector advertisement packet may be fooled if the shortest path is actually calculated through the receiving router itself. Link (4). routing is also not a good candidate for inner-autonomous system routing because an internet is usually too big for this routing method. To use link state routing for the whole internet would require each router to have a huge link state database. It would also take a long time for each router to calculate its routing (5) using the Dijkstra algorism.

(1)是()

A.routing

B.switching

C.transmitting

D.receiving
