(a) Suppose the coefficient of kinetic friction between m1, and the plane in Fig. 4–57 is
\(\mu_{k}=0.15\), and that \(m_{1}=m_{2}=2.7 \mathrm{~kg}\). As \(m_{2}\) moves down, determine the magnitude of the acceleration of \(m_{1} \text { and } m_{2}\), given \(\theta=25^{\circ}\).
(b) What smallest value of \(\mu_{k}\) will keep this system from accelerating?
