A block of mass m1on a frictionless inclined plane making an angle θ 1 with the horizontal is connected by a cord over a small frictionless massless pulley to a second block of mass m 2 on a frictionless plane at an angle θ 2 (see Fig). (a) Show that the acceleration of each block is And that the tension in the cord is (b) Evaluate the acceleration and tension for m 1 = 3.70 kg and m 2 = 4.86 kg when θ 1 = 28° and θ 2 = 42°. What direction does m 1 , move along the plane? (c ) Using the values of m1 θ 1 , and θ 2 given above, for what values of m 2 does m 1 accelerate up the plane? Accelerate down the plane? Not accelerate?
