Question 51

A particle A A\,A of mass 3 kg lies on a horizontal surface and is connected by a light inextensible string passing over a small smooth pulley to a hanging particle B B\,B of mass 2 kg. A frictional force of magnitude 6 N acts on AAA, opposing the motion. The system is released from rest with B B\,B moving downwards. Use g=9.8 m s−2g=9.8\text{ m s}^{-2}g=9.8 m s−2.

Figure for question 4
