Question

A 600g steel block rotates on a steel table while attached to a 1.20m -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 5.11N perpendicular to the tube. The maximum tension the tube can withstand without breaking is 60.0N . Assume the coefficient of kinetic friction between steel block and steel table is 0.60.

a)If the block starts from rest, how many revolutions does it make before the tube breaks?

Express answer in appropriate units.

Explanation / Answer

The weight of the block cause's it to pull at the tube will rotating around.
this force you will have to find. then you have the acceleration of 4.71 N due to the Compressed air. this acceleration will increase the pull force of the block until it reaches 50.0 N.
