two blocks are connected over a pulley. The mass of block A is 8.7 kg and the coefficient of kinetic friction between A and the incline is 0.37. Angle θ of the incline is 31°. Block A slides down the incline at constant speed. What is the mass of block B?

Question

anonymous · Answer

It is given that the block A slides down with uniform velocity i.e the net acceleration of A is zero. Draw the free body diagrams and write down the equations of motion for each body.Solving these will lead you to the answer.
