Q14 In Fig.3, m1 = 22 kg and m2 = 37 kg. The masses are connected by a light, horizontal cord and are being pulled across a smooth level surface by a horizontal force F = 46 N. Find the tension in the cord. (A1) 17 N . Q15 Three books (X, Y, and Z) rest on a table as shown in Fig. 4. The weight of each book is also indicated in the Figure.
A system consists of three masses m 1, m 2 and m 3 connected by a string passing over a pulley P. The mass m 1 hangs freely and m 2 and m 3 are on a rough horizontal table (the coefficient of friction = μ ). The pulley is frictionless and of negligible mass. The downward acceleration of mass m 1 is (Assume m 1 = m 2 = m 3 = m). (a) g(1-gμ)/9
