Problem P. 4783. (December 2015)

P. 4783. A wedge of mass \(\displaystyle m_1\), and a cube of mass \(\displaystyle m_2\) on the horizontal face of the wedge are sliding down along an inclined plane of angle of elevation of \(\displaystyle \alpha=30^\circ\) at the same acceleration. The coefficient of friction between the wedge and the inclined plane is 0.1.

What is the minimum value of the frictional coefficient between the wedge and the cube, if the cube does not slip on the wedge?
