有一个风洞实验室，一架模型飞机固定在托盘测力计上如图所示．无风时，托盘测力计示数为15N；当迎面有风吹过时，托盘测力计的示数减小，可以判定飞机受到了一个新的力，我们把这个新的力称为____，方向是____．

下面是某小组研究该力的大小与风速关系的实验数据：

（1）根据上面的实验数据可知：飞机受到的这个新的力大小随着风速的增大而____ ．由此推测，飞机短距离快速起飞时应该____ （顺风、逆风）起飞．

（2）当风速达到30m/s以上，托盘测力计的示数是0，说明了什么？____．

    One day, Mr. Black went into a restaurant. He put his coat on a chair near the door. There was nothing in the pockets of his coat. After he had his meal, he went to take his coat back. He found there was much money in one of his pockets. “Whose is this?” he thought. He saw a waiter near the door. So Mr. Black said to him, “Somebody put a lot of money in my coat. I have no time to wait for him. I have to go. Take it, please. When he comes back, give it to him.” The waiter took it and went away. At the moment, another man came with a coat just like Mr. Black's. “I'm sorry,” said the man. “I took your coat and you got mine. Please give me my coat and the money. ” Mr. Black answered, “I gave it to the waiter. He'll give it to you. ”

    Mr. Black called the manager（经理）, but the manager said, “We have no waiters here. We only have waitresses（女服务员）. He must be a thief（小偷）.”
