Two identical masses are connected by a (massless, stretchless) string across a (massless, frictionless) pulley. The mass on the right is held so that the string connected to it is horizontal. Everything is initially at rest; the tension is the string is zero. The mass on the right is then released and begins to swing downward. At what angle θwill the mass on the inclined plane begin to slide if the coefficient of static friction between the mass and the plane is 0.50? The indicated angle of the incline is 25.0 O.
