    A 70kg object is being pulled up a slope of 30 degrees such that the rope is parallel to the slope. v is constant. coefficient of friction = 0.3.

    what is the tension of the rope?



    I know without friction its, something like, T=mgsin(30)=70kg(9.8m/s^2sin(30))= 343N
    But i just dont no know to use the friction coefficient? Any help would be much appricated...
