A particle A of mass 4 kg lies on a rough horizontal table and is connected by a light inextensible string over a smooth pulley to a hanging particle B of mass 3 kg. The coefficient of friction between A and the table is 0.25. The system is released from rest with B moving downwards. Take g=9.8g=9.8g=9.8 m s−2^{-2}−2.
Find the acceleration of the particles.
Find the tension in the string.
