    Solving Friction Problems: 500N Box on a Non-Frictionless Floor

    Homework Statement You need to move a 500 N box across the floor. You pull on the box with a rope which is also horizontal. The floor is not frictionless. You move the box so that it moves with a constant v of 3m/s by applying a 200 N force. Coefficient of Friction? Also, same...

    Object pulled up an incline with friction

    Homework Statement 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...

    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 don't no...
