Created by StemPy LabIn an amusement-park rotor, people stand against the inside wall of a large vertical cylinder of radius . The cylinder spins about its vertical axis, and then the floor is lowered. The people stay pinned to the wall. The coefficient of static friction between a person's clothes and the wall is . Taking , the smallest rate of turning for which nobody slides down is closest to

← A block of mass 5 kg is at rest at x = 0 on a smooth horizontal floor. A horizontal force F acts on it along the x-axis, and F changes with the position of the block as shown in the graph. What is the speed of the block when it reaches x = 8 m?A light string is wound many times round a uniform solid cylinder of mass m. The free end of the string is tied to the ceiling, and the cylinder is released from rest with the string vertical, as shown in the figure. As the cylinder falls, the string unwinds without slipping. The acceleration of the cylinder and the tension in the string are →
