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.

A 5.00 kg block sits on the floor at rest. You pull on a rope upwards at an angle. The coefficient of static friction is 0.400 and the coefficient of kinetic friction is 0.300. When you pull upwards with a force of 20.0 N at an angle of 35.0°, what is the force of friction on the box? What is the acceleration of the box?

Two wooden crates rest on top of one another. The smaller top crate has a mass of m1 = 15 kg and the larger bottom crate has a mass of m2 = 88 kg. There is NO friction between the crate and the floor, but the coefficient of static friction between the two crates is μs = 0.85 and the coefficient of kinetic friction between the two crates is μk = 0.66. A massless rope is attached to the lower...
