Lisa was terrified and quite angry. She made up her mind to save her son from the snake"s mouth. It was a fearless mother"s love that made Lisa forget what she faced. She took up an old hatchet (斧头)from the ground and struck the snake with all her strength. One...two... With the hatchet, Lisa hit the snake again and again, but she felt as if she were striking a mass of solid rubber. The little boy"s voice and breath were getting weaker and weaker.

10 (10分)如图所示，质量为m A=2kg的木块A静止在光滑水平面上。一质量为m B= 1kg的木块B以某一初速度v 0=5m/s沿水平方向向右运动，与A碰撞后都向右运动。木块A 与挡板碰撞后立即反弹（设木块A与挡板碰撞过程无机械能损失）。后来木块A与B发生二次碰撞，碰后A、B同向运动，速度大小分别为0.9m/s、1.2m/s。求： ①第一次木块A、B碰撞过程中A对B的冲量大小、方向 ②木块A、B第二次碰撞过程中系统损失的机械能是多少。
