1) Two movers use ropes to pull a heavy box horizontally across a level floor. One pulls with a force of 175.0 N at 20.0 degrees North of East, while the other pulls with 200.0 N at 10.0 degrees West of North. The box has a mass of 125.0 kg, and has coefficients of friction (with the floor) static= 0.350 kinetic= 0.220. a) In what direction is the friction force acting? b) The box is initially stationary. What is its acceleration? c) once it's sliding, what is the acceleration?

A 10.0kg box accelerates across the floor at 1.5m/s^2 when pulled by a force of 20N acting horizontally, The same box is then pulled by the same force acting at an elevation of 40 degrees. A. Draw the free-body diagrams for both situations. B. Determine the coefficient of sliding friction. C. Calculate the acceleration of the box if the force is directed at 40 degrees above the horizontal. Draw the free-body diagram for this situation.
