A block of mass m1 = 3.27 kg on a frictionless plane inclined at angle? = 31.2° is connected by a cord over a mass less, frictionless pulley to a second block of mass m2 = 2.38 kg hanging vertically (see the figure). (a) What is the acceleration of the hanging block (choose the positive direction down)? (b) What is the tension in the cord?
