5.45 Three objects are connected, as shown in Figure 5.32. The mass and friction of each pulley is negligible. The co- efficients of friction between the 3.0-kg block and the horizontal surface are = 0.40 and 0.20. If the system is released from rest and M is moving with a speed of 2.9 m/s after it has fallen 1.4 m, determine the mass M. 2.0 kg Figure 5.32 3.0 kg Problem 5.45 M 5.45 Three objects are connected, as shown in Figure 5.32.
