图1题目:如图1所示,固定在地面上的一根足够长的内壁光滑的水平圆管内,有两个可左右自由滑动的活塞A和B,两活塞之间封闭着一定质量的气体,现有一块粘土C,以Ek0初动能水平飞行撞到A上,并与之粘在一起.已知A、B、C三者质量相等,封闭气体质量不计,且与外界没有热传递.求封闭气体内 Figure 1 title: As shown in Figure 1, fixed in the ground on a long enough smooth inner wall of the round tube, there are two can freely slide left and right pistons A and B, a certain quality of gas sealed between the two pistons , There is a piece of clay C, which hits A with Ek0’s initial kinetic energy level and sticks together. It is known that the quality of A, B, C are equal, the quality of closed gas is not counted, and there is no heat transfer with the outside world. Inside closed gas
