Force of friction help!
A force of 755N is exerted on a rope to pull a 45.0N wooden crate across a concrete floor. If the rope makes an angle of 35.0° with the floor and the crate is moving at a constant velocity what is the amount of the force of friction?
F=ma
So far I have x: F=Fcosθ-Ff=ma I am not sure if that's the right equation given mg, Fa and angle
