A 500 g steel block rotates on a steel table while attached to a 2.0-m-long massless rod. Compressed air fed through the rod is ejected from a nozzle on the back of the block, exerting a thrust force of 3.5 N. The nozzle is 70° from the radial line, as shown in FIGURE P8.62. The block starts from rest.
a. What is the block€™s angular velocity after 10 rev?
b. What is the tension in the rod after 10 rev?
