In a popular amusement park ride, a rotating cylinder of radius r = 3.90 m is set in rotation at an angular speed of 6.50 rad/s, as in the figure shown below. the floor then drops away, leaving the riders suspended against the wall in a vertical position. what minimum coefficient of friction between a rider's clothing and the wall is needed to keep the rider from slipping? hint: recall that the magnitude of the maximum force of static friction is equal to ? sn, where n is the normal force

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
