Hello! 

      My name is Becky Sharp. I'm eleven years old. I have one brother. His name's Jason and he's fourteen. I

don't have any sisters.

      We live with grandma in a small house in Chesterfield, in the north(北部) of England. My friends and I often

go to the cinema on Saturdays. 

      Do you like games? I like football. My favourite team is Manchester United (曼联队). I sometimes play

football with my brother. I'm excellent (棒极了) but he isn't very good. 

      I have seven pets — two birds and five goldfishes. I want a dog and a cat, but my mother doesn't like them.

      Please write to me soon.

如图所示，长为L=0.7m、质量为m=1.0kg的薄壁箱子，放在水平地面上，箱子与水平地面间的动摩擦因数μ=0.25，箱内有一质量也为m=1.0kg的小滑块，滑块与箱底间无摩擦．开始时箱子静止不动，小滑块以v₀=4m/s的恒定速度从箱子的A壁处向B壁处运动，之后与B壁碰撞，滑块与箱壁每次碰撞的时间极短，可忽略不计，滑块与箱壁每次碰撞过程中，系统的机械能没有损失，g=10m/s²．求：

（1）滑块与箱壁最多可碰撞几次？

（2）从滑块开始运动到滑块与箱壁刚完成第三次碰撞的时间．
