Problem: A mover has to move a heavy sofa of mass 66.0 kg to the second floor of the house. As he pulls on the rope tied to the sofa, he makes sure that the rope is parallel to the surface of the ramp, which is at 30.0° to the horizontal. If the coefficient of kinetic friction between the sofa and the ramp is 0.340, and the sofa has an acceleration of 0.900 m/s2,
Part A: Find the tension in the rope.
Please use as much detail as required in your solution. Thanks.
