Problem: A mover has to move a heavy sofa of mass 143 kg to the second floor of the house. He uses a rope to pull the sofa up a ramp from the first to the second floor. As he pulls 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 friction between the sofa and the ramp is negligible, and the sofa has an acceleration of 0.900 m/s2, find the tension in the rope.

___ N

So confused, please explain how you got the answer for above problem. Thanks.
