Three blocks of masses 3 kg, 6 kg and 1 kg are connected by a string passing over two smooth pulleys attached at the two ends of the horizontal surface. If the co-efficient of friction between the block and the surface is 0.6, the frictional force acting on the block of mass 6 kg is

Two unequal masses of 1kg and 2kg are connected by a string going over a clamed light smooth pulley as shown in figure . The system is released from rest .The larger mass is stopped for a moment 1.0 s after the system is set in motion.Find the time elapsed before the string is tight again.

Two blocks of mass 2 kg and 5 kg are connected by an ideal string passing over a pulley. The block of mass 2 kg is free to slide on a surface inclined at an angle of 30^(@) with the horizontal whereas 5 kg block hangs freely.
