How large a horizontal force in addition to F_T must pull on block-A in Fig. 3-21 to give it an acceleration of 0.75 m/s² toward the left? Assume, as in Problem 3.31, that μ_k = 0.20, m_A = 25 kg, and m_B = 15 kg.

Problem 3.31

In Fig. 3-21, the coefficient of kinetic friction between block-A and the table is 0.20. Also, m_A = 25 kg, and m_B = 15 kg. How far will object-B drop in the first 3.0 s after the system is released?
