Question

In the figure, two blocks are connected over a pulley. The mass of block A is mA and the coeffcient of kinetic friction between A and the incline is μ k Angle of the incline isBlock A slides down the incline at constant speed. What is the mass of block B? Express your answer in terms of the variables given. Frictionless massless pulley (D) | sin | log | +- 27

Answer 1

The given that Block A is moving with constant speed, and then Block B also moves with the same constant speed. There is no acceleration in th e two blocks For Block A fc Is the kinetic frictional force T is the tension in the rope s-muk(m )(g)cos θ Then mAgsin9-muk(m)(g)cos θ+7 (1) For Block B T- mag---(2) Substituting from equation (2) and (1) m,-mAĮsin θ-n,kcos@
