Homework Statement
A 500kg box is being pushed across a floor, with an applied force of 8400N, at a constant velocity, at an angle of 35 degrees below the horizontal. What is the coefficient friction between the floor and the box.
Homework Equations
I really do not know where to start.
The Attempt at a Solution
I know that Ff= (coefficient of kinetic friction)*mass*gravity
and because it's at constant velocity Fp=Ff right?
the answer is 0.71
