Two 12.0 kg boxes are connected by a massless string that passes over a massless frictionless pulley as shown above. The boxes remain at rest, with the one on the right hanging vertically and the one on the left d = 2.9 m from the bottom of an inclined plane that makes an angle of θ = 33° with the horizontal.
(a) What is the tension T in the string?
______ N
(b) Determine the magnitude of the frictional force between the box and the plane.
______N
You then polish the plane surface, let the blocks go and they accelerate at 3.0 m/s2
(c) The rope tension is now equal to
