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 3.4 N. The nozzle is 70 degrees from the radial line.What is the block's angular velocity after 10 rev?What is the tension in the rod after 10 rev?

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 3.4 N. The nozzle is 70 degrees from the radial line.

What is the block's angular velocity after 10 rev?

What is the tension in the rod after 10 rev?
