Ann
She lives next door and she's always been really important in my life. When we were
little and my mum was working she used to look after us. She would tell us stories about her
childhood. It was like listening to fairy stories: life was so different when she was a child. In her
kitchen she used to keep a special dish with sweets for us, and she was always baking cakes and
pies. Now she doesn't bake so much. She's started eating more healthily in her old age, salads
and vegetables and things. It's funny how she's changed. She also goes to this special gym class
for old people, it's amazing. I don't see her so often now, but she's always the same person
however much her lifestyle changes
Ben
He's four years older than me and that seemed like a huge amount when we were
children. When we were at the same school we'd never talk to cach other during school hours.
But now we're older it's a lot better, although I'll always be the little one, and that's annoying
sometimes. He's taken me to rock concerts that I wouldn't have gone to otherwise and when he
was at university I went to stay with him sometimes. That was really cool. It was great to see
what real student life was like when I was still at school. Now that he's working he's really busy,
but we still hang out sometimes. We go to football matches together because we both support our
home team. It's
always good to see him.
Susan
We've known each other since we were five and we've always got on really well. Well
apart from that time when we fell out because we both liked the same boy. But he went off with
Heather Jenkins, so we made friends again quite quickly! We both like the same kind of music
and going dancing at the weekend, and when we were younger we went out on our bikes
together. At school we're good at different things. I'm good at languages and she's good at
Maths. That's good though it means that we can help each other with our homework. Next year
I'm probably going to study in London and she's going to Manchester, but I'm sure our
relationship won't change.

Две гири массы 11 кг и 5 кг висят на концах нити, перекинутой через неподвижный блок. Первая гиря расположена на 8 метров выше второй. Если отпустить гири, то они начнут ускоренно двигаться. Определить с точностью до десятых ускорение первой гири (проекцию на ось y). Массой нити и блока, а также трением в оси блока пренебречь, считать g=9.8 м/с2.
