Problem P. 4097. (October 2008)

P. 4097. The wedge, shown in the figure, has a mass of m and an angle of $\alpha$ and can slide without friction along the horizontal tabletop. A block of mass m is placed onto the wedge, and it slides down without friction. At what angle $\alpha$ will the magnitude of the acceleration of the wedge be at least one-third of the acceleration due to gravity?
