A ball of mass m1 and a block of mass m2 are attached by a lightweight cord that passes over a frictionless pulley of negligible mass, as shown in  theFigure 1.1.  The block lies on a frictionless incline of angle q. Find the magnitude of the acceleration of the two objects and the tension in the cord. What happens in this situation if the angle q  =  90O? What happens if the mass m1 = 0?
