Question 17

Multiple Choice

Figure 4.4 Figure 4.4 The figure shows two bodies of masses M and m, M placed on a horizontal surface and m hanging at the side, connected by a light cord over a massless and frictionless pulley. -In Fig. 4.4, the masses are M = 10 kg and m = 20 kg. The coefficient of friction for the horizontal surface is ì = 0.4. What are the acceleration of the system and the tension in the string? A) 5.2 m/s<sup>2</sup>, 92 N B) 5.2 m/s<sup>2</sup>, 39 N C) 7.9 m/s<sup>2</sup>, 92 N D) 7.9 m/s<sup>2</sup>, 39 N The figure shows two bodies of masses M and m, M placed on a horizontal surface and m hanging at the side, connected by a light cord over a massless and frictionless pulley.
