A uniform cylinder of radius 1 m. mass 1 kg spins about its axis with an angular velocity 20 rad/sec. At certain moment the cylinder is placed into a comer as shown in the figure. The coefficient of friction between the horizontal wall and the cylinder is µ. where as the vertical wall is fiictionless. If the number of rounds made by the cylinder is 5 before it stops, the value of υ is :
(Acceleration due to gravity g = 10 m/s2)
