The mass of the m_1 block in the figure is 40 kg, and the mass of the m_2 block is 10 kg. There is no friction between the m_1 block and the ground. The friction coefficient between m_2 and m1 is 0.6 and the kinetic friction coefficient is 0.4. A horizontal force of F = 100 N started to pull the m_2 block as shown. In this case, calculate the accelerations of m_1 and m_2 blocks?
