No <\/b><\/span><\/span><\/span>Levantamento de Peso Ol\u00edmpico, <\/b><\/span><\/span><\/span>a <\/b><\/span><\/span><\/span>prova do arranque consiste no atleta levantar uma barra com pesos do solo at\u00e9 acima da cabe\u00e7a em um \u00fanico movimento.<\/b><\/span><\/span><\/span><\/p>\n

O <\/b><\/span><\/span><\/span>recordista mundial <\/b><\/span><\/span><\/span>\u00e9 o atleta iraniano Behdad Salimi que, nos Jogos Ol\u00edmpicos do Rio, <\/b><\/span><\/span><\/span>levantou 216 kg. <\/b><\/span><\/span><\/span><\/p>\n

Considere,<\/b><\/span><\/span><\/span> para <\/b><\/span><\/span><\/span>este levantamento, duas situa\u00e7\u00f5es. <\/b><\/span><\/span><\/span><\/p>\n

Na <\/b><\/span><\/span><\/span>situa\u00e7\u00e3o inicial (A),<\/b><\/span><\/span><\/span> o atleta est\u00e1 <\/b><\/span><\/span><\/span>levantando o peso quando o halter j\u00e1 n\u00e3o est\u00e1 mais em contato com o ch\u00e3o. <\/b><\/span><\/span><\/span><\/p>\n

Ele faz uma <\/b><\/span><\/span><\/span>for\u00e7a vertical para cima, <\/b><\/span><\/span><\/span>de modo que a <\/b><\/span><\/span><\/span>barra acelera, verticalmente para cima, com acelera\u00e7\u00e3o de 1 m\/s<\/b><\/span><\/span><\/span>2<\/b><\/span><\/span><\/sup><\/span>. <\/b><\/span><\/span><\/span><\/p>\n

Na <\/b><\/span><\/span><\/span>situa\u00e7\u00e3o (B), a barra j\u00e1 est\u00e1 em repouso, acima da cabe\u00e7a do halterofilista.<\/b><\/span><\/span><\/span><\/p>\n

Com base nestas informa\u00e7\u00f5es, fa\u00e7a o que se pede: <\/b><\/span><\/span><\/span><\/p>\n

a) <\/b><\/span><\/span><\/span>A <\/b><\/span><\/span><\/span>figura abaixo <\/b><\/span><\/span><\/span>mostra <\/b><\/span><\/span><\/span>quatro op\u00e7\u00f5es para o diagrama de for\u00e7as para a barra<\/b><\/span><\/span><\/span>. <\/b><\/span><\/span><\/span><\/p>\n

Em <\/b><\/span><\/span><\/span>cada op\u00e7\u00e3o s\u00e3o mostrados dois diagramas, um para a situa\u00e7\u00e3o (A) e outro para a situa\u00e7\u00e3o (B).<\/b><\/span><\/span><\/span><\/p>\n

\"\"<\/p>\n

Em <\/b><\/span><\/span><\/span>todos eles, F \u00e9 a for\u00e7a que o halterofilista faz na barra naquela situa\u00e7\u00e3o <\/b><\/span><\/span><\/span>e <\/b><\/span><\/span><\/span>P \u00e9 o peso da barra. Responda qual<\/b><\/span><\/span><\/span> das <\/b><\/span><\/span><\/span>op\u00e7\u00f5es representa corretamente a rela\u00e7\u00e3o entre o m\u00f3dulo das for\u00e7as, justificando <\/b><\/span><\/span><\/span>sua resposta no campo abaixo <\/b><\/span><\/span><\/span>(se voc\u00ea escrever APENAS qual a op\u00e7\u00e3o n\u00e3o receber\u00e1 nenhuma pontua\u00e7\u00e3o).<\/b><\/span><\/span><\/span><\/p>\n

b) Calcule a for\u00e7a F <\/b><\/span><\/span><\/span>que o <\/b><\/span><\/span><\/span>levantador faz na barra em cada caso.<\/b><\/span><\/span><\/span><\/p>\n
