Block A has a weight of 3000 N and block B has a weight of 50 N . Coefficient of friction for A is mu_(k) = 0.2 . Determine the pseed of block A after moves 1 m down the plane, starting from rest. Negelect the mass of the cord and pulleys.

Block A weights 4 N and block B weights 8 N. The coefficient of kinetic friction is 0.25 for all surfaces. The force F to slide B at a constant speed, when A rests on B and moves with it, is

In figure calculate the linear acceleration of the blocks. Mass of block B= 8kg mass of disc shaped pulley =2kg (take g=10m//s^(2) )

In figure calculate the linear acceleration of the blocks. Mass of block B= 8kg mass of disc shaped pulley =2kg (take g=10m//s^(2) )

With what force must a man pull on the rope to hold the plank in position it the man weights 60 kg? Neglect the weight of the plank, rope and pulley ( Take g= 10m//s^(2))

In the arrangement shown in figure m_(A)=4.kg and m_(B)=1.0kg . The system is released from rest and block B is found to have a speed 0.3m//s after it has descended through a distance of 1.m find the coefficient of friction between the block and the table. Neglect friction elsewhere. (Take g=10 m//s^(2) ). .
