A block m_1 on a rough, hatched table is tied by a string over a pulley at the table’s edge to a block m_2 hanging below. Tension T runs along both parts of the string; m_1 g and m_2 g point down, the normal force F_N points up from m_1, and friction F_f points away from the pulley. Dashed arrows a show m_1 moving toward the pulley and m_2 falling.
