a solid cylinder with radius 0.41 m and mass 8 kg has rolled across the floor and into a wall. when it strikes, it has an angular speed ω0 =13rad/s The coefficient of friction between the cylinder and both the floor and wall,
μ=0.4. How long until the cylinder comes to rest? Assume zero rebound from the wall. Specify your answer in seconds to 3 decimal places.
