Find the tension in the rope

Reference no: EM13714380

Problem: A mover has to move a heavy sofa of mass 66 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.

Part A: If the coefficient of kinetic friction between the sofa and the ramp is 0.530, and the sofa has an acceleration of 0.800 m/s², find the tension in the rope.

I know the correct answer for above problem but explain how to get this answer! Thanks.
