Um método para calcular os coeficientes de atrito estático e cinético entre duas superfícies é posicionando um bloco sobre um plano de inclinação variável com atrito. Um bloco com massa de 24 kg está parado num plano de inclinação variável. Se o coeficiente de atrito estático for =(0,03×22) , (a) calcule a maior inclinação (ângulo com a horizontal) antes de o bloco começar a deslizar. (b) Calcule a aceleração com que este bloco desliza sobre o plano, se mantido o ângulo de inclinação encontrado em (a) e se o coeficiente de atrito dinâmico for =(0,02×12) .

Cause ah, ah, I’m in the stars tonight

So watch me bring the fire and set the night alight

Shoes on, get up in the morn’
