A uniform cylinder of radius 1 m, mass 1 kg spins about its axis with an angular velocity 20 rad/s. At certain moment, the cylinder is placed into a corner as shown in the figure. The coefficient of friction between the horizontal wall and the cylinder is mu , whereas the vertical wall is frictionless. If the number of rounds made by the cylinder is 5 before it stops, then the value of mu is (acceleration due to gravity, g = 10 m//s^2 )

The critical velocity v of a body depends on the coefficient of viscosity eta the density d and radius of the drop r. If K is a dimensionless constant then v is equal to

A uniform circular disc of radius R, lying on a frictionless horizontal plane is rotating with an angular velocity omega about is its own axis. Another identical circular disc is gently placed on the top of the first disc coaxially. The loss in rotational kinetic energy due to friction between the two discs, as they acquire common angular velocity is (I is moment of inertia of the disc)
