日常生活中难免会出现一些意外情况，掌握一定的避险救助知识和技能有助于我们合理应对。回答下列各题。

如图所示，某传送带与水平地面夹角θ=30°，AB之间距离L₁= $\frac{5}{3}$ m，传送带以v₀=10m/s的速率转动，质量为M=1.0kg，长度L₂=1.0m的木板上表面与小物块的动摩擦因数μ₂=0.4，下表面与水平地面间的动摩擦因数μ₃=0.1，开始时长木板靠近传送带B端并处以静止状态．现从传送带上端A无初速地放一个质量为m=1.0kg的小物块，它与传送带之间的动摩擦因数为μ₁= $\frac{\sqrt{3}}{6}$ ，（假设物块在滑离传送带至木板右端时速率不变，重力加速度g=10m/s²），求：

    Bob and his family like eating fish very much. He often buys some fish in the shop and takes them home for dinner. His wife (妻子) often asks her friends to their home to have lunch and eat fish. One day, Bob buys some fish home and goes to his office to work. His wife sees the fish and thinks, “Good! I can ask my friends to come for lunch.”

    When Bob comes home from work in the evening, he can't find his fish. His wife says, “ Oh, It's your cat. Your cat eats it.” And she gives Bob some bread for dinner. The husband is very angry(生气的). He takes the cat and his wife to the shop near (附近) their home to weigh  the cat. Then he asks his wife, “You see, my fish is one kilo, and this cat is one kilo, too. My fish is here. Then where is my cat?”
