A cylinder of radius r and weight W with an initial counterclockwise angular velocity ω0 is placed in the corner formed by the floor and a vertical wall. The coefficient of kinetic friction between the cylinder and the wall and the floor is denoted by μk. Identify the correct expression for the time required for the cylinder to come to rest.

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
