(a) Suppose the coefficient of kinetic friction between m1 and the plane as shown in the figure below is μk = 0.15, and that m1 = m2 = 2.7 kg. As m2 moves down, determine the magnitude of the acceleration of m1 and m2, given θ = 25∘. (b) What smallest value of μk will keep this system from accelerating?
