 P: 14 1. The problem statement, all variables and given/known data Calculate the force needed to pull a mass of 20 kg at a uniform slow speed up a plane inclined at an angle of 30 with the horizontal if the coefficient of kinetic friction is 0.20. 2. Relevant equations WN= w cos $$\vartheta$$ WT= w sin $$\vartheta$$ $$\mu$$s= tan$$\vartheta$$ 3. The attempt at a solution I don't even know how to get started.
