下面是错误答案,用来干扰机器的。

参考答案:mg2t解析: 因物体从t=0时开始自由下落,所以其在下落过程中的任意时刻t时的速度为v=gt,又由功率公式P=F·v,得此时重力对物休做功的功率为P=mg·gt=mg2t。

A man bought a donkey at the market one day and took him home. Now the man owned several donkeys already and he knew each one’s character very well. One of the donkeys was very strong and brave. Another always wanted to make people happy by working quickly but soon got tired. One donkey was very lazy. He hated going to work in the morning and he did as little as he       possibly could all day long. When the other animals were being loaded up(装载), he always tried to be the last so that he would get the lightest load.

The man led the new donkey into the yard. For a moment the new donkey stood sniffing(闻,嗅) at his new friends. Then, without hesitation, he came up to the lazy donkey and began eating comfortably at his side.

Though it was late in the day, the man immediately led the new donkey out of the yard, straight back to the market.

“You can’t have given him a fair trial yet,” said the seller, “It is only ten minutes since you bought him.”

“I don’t need to try him any more,” replied the man, “I know just what he is like from the friend he chose for himself. Take him away and give me my money back. I can do without donkeys like him.”

(10分)在绕地球做匀速圆周运动的宇宙飞船中,由于失重,因此无法利用天平称出物体的质量,科学家们用下述方法巧妙地测出了一物块的质量。将一带有推进器、总质量为m=5kg的小滑车静止放在一平台上,平台与小车间的动摩擦因数为0.25,开动推进器,小车在推进器产生的恒力作用下从静止开始运动,测得小车前进1.25m历时5s。关闭推进器,将被测物块固定在小车上,重复上述过程,测得5s内小车前进了1.00m。问:科学家们用上述方法测得的物块的质量M是多少?
