Two boxes with masses m1 = 4.20 kgand m2 = 11.8 kgare attached by a massless cord passing over a frictionless pulley as shown in the figure below. The incline is frictionless, and θ = 46.0°.
What is the magnitude of the acceleration of the boxes?
What is the tension in the cord connecting the boxes?
What is the speed of each of the boxes 2.50 s after the system is released from rest?
