Um bloco A, de peso igual a 5N, pode deslizar sem atrito sobre uma mesa horizontal. Utilizando-se uma corda de massa desprezível presa ao bloco A e uma roldana ideal, também de massa desprezível, é possível puxar o bloco A de duas formas distintas, como ilustram as figuras. Na situação 1, um segundo bloco, de peso também igual a 5N, é amarrado na outra extremidade da corda que passa pela roldana. Na situação 2, a extremidade livre da corda é puxada para baixo com uma força de 5N. Assinale a alternativa que descreve os módulos das acelerações (a1 e a2 ) do bloco A, nas duas situações, respectivamente.

Alice Munro’s road to Nobel literature prize was not easy
Nobel literature prize winner Alice Munro.
Alice Munro has been awarded the 2013 Nobel Prize in literature, thus becoming its 13th female recipient. It’s a thrilling honour for a major writer: Munro has long been recognised in North America and the UK, but the Nobel will draw international attention, not only to women’s writing and Canadian writing, but to the short story, Munro’s chosen literary genre and one often neglected.
The road to the Nobel wasn’t an easy one for Munro. She found herself referred to as “some housewife”, and was told that her subject matter, being too “domestic”, was boring. A male writer told her she wrote good stories, but he wouldn’t want to sleep with her. “Nobody invited him,” said Munro. Maybe as a consequence of this initial reaction towards her, when writers occur in Munro stories, they are pretentious, or exploitative of others; or they’re being asked by their relatives why they aren’t famous, or – worse, if female – why they aren’t better-looking.
The chances that a literary star would emerge from her time and place would once have been zero. Munro was born in 1931, and thus experienced the Depression as a child and the Second World War as a teenager. This was in south-western Ontario, Canada, a region that also produced equally talented writers and poets such as Robertson Davies, Graeme Gibson, James Reaney, and Marian Engel. It’s this small-town setting that features most often in her stories – the snobberies, the eccentrics, and the jeering at ambitions, especially artistic ones.
Shame is a common driving force for Munro’s characters just as perfectionism in the writing and courage in her profession have been driving forces for her.
As in much else, Munro is essentially Canadian. Faced with the Nobel, she will be modest, she won’t get a swelled head. The rest of us, on this magnificent occasion, will just have to do that for her.
