(PUC RJ/2010) Um bloco escorrega a partir do repouso por um plano inclinado que faz um ângulo de 45º com a horizontal. Sabendo que durante a queda ...

Para determinar o coeficiente de atrito cinético entre o bloco e o plano, podemos usar a seguinte fórmula: μ = (a - g * senθ) / g * cosθ Onde: μ é o coeficiente de atrito cinético a é a aceleração do bloco durante a queda g é a aceleração da gravidade θ é o ângulo de inclinação do plano Substituindo os valores fornecidos na questão, temos: μ = (5,0 - 10 * sen45°) / 10 * cos45° μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 * √2/2 μ = (5,0 - 10 * √2/2) / 10 *
