A 69 kg crate is dragged across a floor by pulling on a rope attached to the crate and inclined 12° above the horizontal. (a) If the coefficient of static friction is 0.46, what minimum force magnitude is required from the rope to start the crate moving? (b) If μk = 0.36, what is the magnitude of the initial acceleration (m/s^2) of the crate?

A 35 kg crate is at rest on the floor. A man attempts to push it across the floor by applying a 100 N force horizontally. (a) Take the coefficient of static friction between the crate and the floor to be 0.37 and show that the crate does not move. (b) A second man helps by pulling up on the crate. Calculate the minimum vertical force he must apply so that the crate starts to move across the floor. (c)...

A man is pulling a crate of mass m=50kg using a massless rope. The rope is at an angle of theta=30 degrees with respect to the floor. There is friction between the crate and the floor. The man pulls the rope with an increasing force until the block starts to move (let's call Fa the force he needs to apply to start moving the block). Once the block starts moving, the man then changes his pulling force (increasing or decreasing...

A crate of 31.6-kg tools rests on a horizontal floor. You exert a gradually increasing horizontal push on it and observe that the crate just begins to move when your force exceeds 309 N . After that you must reduce your push to 248 N to keep it moving at a steady 22.0 cm/s What is the coefficient of static friction between the crate and the floor? What is the coefficient of kinetic friction between the crate and the floor?...
