К = 1 кН/м = 1000 Н/м F = K * x ---> x = F/K

F = 100 H E = k*x²/2 = F²/(2*k) = $\frac{10000}{2*1000}$ = 5Дж

I work in a space station, from my office, i can see the Earth twenty thousand miles away. It floats in space like a big green and blue ball, I am the Station Supervisor. i like my job, but I sometimes get bored inside the space station. One day i was in my office watching the men working outside. They were budding par t of the station. Suddenly i was called on the radio from the Satellite Control Office, "There is something about two miles away and its hardly moving. Can you see what it is?" I took out my binoculars and looked at the sky. A small satellite was coming towards us. It looked old. I was told Lo go out and to bring it in. I put away my papers and went to get my spacesuit. All the spaces nits were kept in large lockers. On my way to the lockers I met our cat, Tommy. Most animals don't like to live in space, but Tommy was happy. All the men liked him. I climbed into my spacesuit and soon I was in space. i saw the satellite and began to move towards it. But at that moment something went wrong. I heard a noise. It was a strange noise. Something was scraping on the metal of the spacesuit. I froze witb fear. There's something outside. It was alive. And it was trying to gel into my spacesuit, I thought. Bernie Summers! I thought. He died in space. His spacesuit broke open. After the accident, Bernie Summers' spacesuit had been repaired. Was his ghost trying to get back into my spacesuit? I had heard strange stories about ghosts in space. i grew more and more afraid. i switched on the radio and shouted: "Help! I'm in trouble! Did this spacesuit belong to..." I never finished the sentence. At that moment, I felt something. Something patted me softly on the hack of my neck. I screamed as loud as I could. I fainted and fell down. Sometime later, I woke up. I was back in the space station. The doctors were round my bed. But they weren't looking at me. They were looking at something more interesting. b) Try to predict the end of the story: What were the doctors looking at? Who patted the spaceman on the back of his neck? Now read the end of the story and find out if you were right. The doctors were playing with three kittens. Then i remembered the cat, Tommy. Tommy? A tom-cat? We had all made a mistake. Our Tommy wasn't a tom-cat. She was a mother! She had put her babies in the pocket of the spacesuit. One of the kittens had patted me on the neck with its soft little paw. I had been knocked out by a kitten
