Two blocks with masses m1 = 15.0 kg and m2= 10.0 kg are connected by a massless string across a massless, frictionless pulley as shown in the figure below. Block 1 sits on a frictionless plane inclined at an angle θ = 30.0° above the horizontal. When both blocks are released, block 1 begins sliding up the plane as block 2 falls. What is the acceleration of both blocks after they have been released?
