Problem 8.70 (5) 17 of19 > V P A A 600 g steel block rotates on a steel table art while attached to a 1.20 m long hollow tube. Compressed air fed through the tube and ejected from a nozzle on the back of the block exerts a thrust force of 4.81 N perpendicular to the tube. The maximum tension the tube can withstand without breaking is 50.0 N . Assume - A24) '5 0 O ? the coefficient of kinetic friction between steel block and steel table is 0.60. (F_igure 1) ,' Ernest Answer If the block starts from rest, how many revolutions does it make before the tube breaks? Fi ure 9 Provide Feedback Next)
