An amusement park ride has a vertical cylinder with an inner radius of 3.5 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 0.86. what minimum angular velocity in radians/second is necessary to assure that the riders will not slide down the wall?

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
