Pleas help Above On a disk is an iron cube of mass 200g, at a distance of 10cm from the axis of rotation of the disk, fig.3.95. The coefficient of friction of the rest of the cube with the disk is 0.4. Find: a) How many revolutions per minute does the disk make the moment the iron cube slides from the disk. b) The centripetal force acting on the cube before the moment of sliding from the disk.
