A mass m slides up an incline (with \theta\:θ= 30.34 degrees above the horizontal) until it stops momentarily because of friction. The coefficient of static friction between the mass and incline is 0.53; the coefficient of kinetic friction between the mass and incline is 0.08. At a given instant, the mass is moving with speed of 6.59 m/s up the incline. At what later time (in seconds) will the mass come to a stop?

An amusement park ride has a vertical cylinder with an inner radius of 4 m, which rotates about its vertical axis. Riders stand inside against the carpeted surface and rotate with the cylinder while it accelerates to its full angular velocity. At that point the floor drops away and friction between the riders and the cylinder prevents them from sliding downward. The coefficient of static friction between the riders and the cylinder is 0.91. What minimum angular velocity in radians/second...

A crate of 37.2-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 322 N . After that you must reduce your push to 240 N to keep it moving at a steady 29.1 cm/s . A.What is the coefficient of static friction between the crate and the floor? B.What push must you exert to give it an acceleration of 1.11...
