A 70 kg object is being pulled up a slope of 30 degrees such that the rope is parallel to the slope. the velocity is constant. however, there is a coefficient of friction is 0.3
The Attempt at a Solution
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...
