Describe a collision in which all kfrio c-ve pm:wif9: 6/p ij.:jinetic el ;vqs (c2w1sn1 jdpr2nergy is lost.
参考答案: Consider two objects, each with the same
magnitude of momentum, moving in opposite directions. They have a total momentum of 0. If they collide and have a totally inelastic
collision, in which they stick together, then their final common speed must be
0 so that momentum is conserved. But
since they are not moving after the collision, they have no kinetic energy, and
so all of their kinetic energy has been lost.
