Question: Three packages, each weighing 7 4 . 5 kg and labeled ( mathrm { L } , mathrm { M }

Three packages, each weighing 74.5 kg and labeled \(\mathrm{L},\mathrm{M}\), and N , are initially placed at rest on a conveyor belt. The coefficients of static and kinetic friction between packages L and N and the belt are \(\mu \mathrm{s}=0.30\) and \(\mu \mathrm{k}=0.20\), respectively. For package \( M \), the coefficients of static and kinetic friction with the belt are \(\mu \mathrm{s}=0.10\) and \(\mu \mathrm{k}=\)0.08. The packages are initially positioned so that they are in contact with one another and remain stationary. Determine the friction force acting on M.(Use g =9.81m/s2)
