Many people consider their pets members of the family and are very sad when they die, but what if you could clone your dog, cat or bird?

A scientist in New Orleans, who has proved his ability to clone other animals, is now offering the possibility to pet owners here in Wisconsin．

Scientists have not been able to clone dogs, cats or other pets, but if and when the time comes, several companies will be ready and able to do the job．

The question is: Are you ready to clone your pet? Brett Reggio is betting on it．He is working on his Ph. D at Louisian State University. He's successfully cloned a goat five times and wants to try the process on family pets．  So he started a business called Lazaron． “What Lazaron provides is the first step in the cloning process． ”He said．“It’s for curing and storing the fiberglass cells that will be used for cloning．”

“Your first reaction is yeah! I think I’d like that．” said Donna Schacht, a pet owner．

“I don’t believe you can ever replace a special love,” pet owner Paulette Callattion said．

Most pet owners will tell you freezing your pet’s  DNA in hopes of one day cloning it is a personal decision．

Scientists say that cloning your own pet doesn’t mean that the offspring（后代） will have the same intelligence, temperament（性情） or other qualities that your pet has．

装有装饰材料的木箱A质量为50kg，放在水平地面上，要将它运送到90m远处的施工现场。如果用450N的水平恒力作用6s使A从静止开始运动直至到达施工现场。求：

（1）6s内，水平恒力所做的功；

（2）木箱与地面间的动摩擦因数；

（3）若用大小为450N，方向与水平方向夹角为37°（sin37°=0.6，cos37°=0.8）斜向上的拉力拉木箱A从静止开始运动，使木箱A刚好能够到达90m远处的施工现场，拉力的最大瞬时功率是多少？（运动过程中动摩擦因数处处相同，取，结果保留2位有效数字）。
