A solid disk of mass 1.45 kg and radius 25.0 cm is initially spinning counterclockwise (as viewed from above) at 15.5 revolutions per second on a massless and frictionless bearing. A second disk, of mass 1.05 kg and radius 12.5 cm is initially spinning clockwise about the same axis at 14.2 revolutions per second, is dropped on top of the first disk. Because there is friction between the disks, they quickly reach a common angular speed. What is their final angular speed, in revolutions per second

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
