Two boxes are connected by a massless rope the runs across a massless frictionless pulley. A box with mass m1 = 2.00 kg rests on a frictionless horizontal surface. A second box with mass m2 = 3.00 kg lies on a frictionless surface inclined at an angle of θ = 30.0◦ above the horizontal. A force with a magnitude of |F⃗ a| = 20.0 N pulls the set of boxes. (a) What is the magnitude of the acceleration of the two boxes? (b) What is the magnitude of the tension in the rope?
