A box weighing 450 Newtons is pulled along a level floor at an angle of 30 degrees with the floor.If the force of the rope is 260 Newtons.What is the coefficient of sliding friction for the surface?

3 answers

the horizontal pulling force is
... 260 cos(30º)

the vertical pulling force is
... 260 sin(30º)

the coefficient of sliding friction is
... [260 cos(30º)] /
... {450 - [260 sin(30º)]}
How to solve this problem in physics
A 35 kg box is pulled along level floor at uniform speed by a rope which makes an angle of 30ᴼ with the floor. If the force on the rope is 80 N, what is the coefficient of friction?
