By pulling a on rope attached to a crate of mass 77.0 kg, the crate is dragged across a floor. Let the coefficient of static friction between the crate and the floor be 0.830 and the angle between the rope and horizontal is 39.1 °. Find the minimum force required to move the crate. At a later time the crate is now dragged with this same force, and has already started moving, on a wet floor where the kinetic friction...

Just asking help with Part I
A factory worker pushes a 30.0 kg crate a distance of 4.40 m along a level floor by pushing downward at an angle of 28.0° below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.260. The Crate is Pushed with Increasing Speed Now assume that, instead of the previous situation, the worker pushes harder (without changing the direction of his push), so that the crate moves with increasing speed....

A warehouse worker is pushing a 90.0 kg crate with a horizontal force of 288 N at a speed of v = 0.850 m/s across the warehouse floor. He encounters a rough horizontal section of the floor that is 0.75 m long and where the coefficient of kinetic friction between the crate and floor is 0.357. (a) Determine the magnitude and direction of the net force acting on the crate while it is pushed over the rough section of the...
