A block of mass m1 = 6.67 kg on a frictionless plane inclined at angle ? = 33.6° is connected by a cord over a massless, frictionless pulley to a second block of mass m2 = 2.22 kg hanging vertically (see the figure).
(a) What is the acceleration of the hanging block (choose the positive direction up)?
(b) What is the tension in the cord?
