Question: A 600 g steel blockrotates on a steel table (μk = 0.6) whileattached to a 1.1 m longhollow tube. Compressed air fed through the tube and ejected from anozzle on the back of the block exerts a thrust forceof 4.6 N perpendicular tothe tube. The maximum tension the tube can withstand withoutbreaking is 50 N. If the block starts from rest, how many revolutions does it make before the tube breaks?
