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?

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...
