A 600 g steel block rotates on a steel table 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 4.30 N perpendicular to the tube. The maximum tension the tube can withstand without breaking is 60.0 N.(adsbygoogle = window.adsbygoogle || []).push({});

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

I've done some calculations and have come up with:

Tangential Acceleration: 1.287 m/s^2

Omega: 9.13

Period: 8.513 seconds

plugged these numbers into Theta=((a)/(2*r))*(period)^2

and got 38.953 rads, or 61.19 revolutions... which was wrong
