Ablock (mass m1) lying on a frictionless inclined plane is connected to a mass (mass m2) by a massless cord passing over a pulley, as shown in figure below. (a) determine a formula for the acceleration of the system of the two blocks in terms of m1, m2, theta, and g. (b) what conditions apply to masses andm1 and m2 for the acceleration to be in one direction (say, m1 down the plane), or in the opposite direction? show all work, !
