how long would it take a spinning 1 kg mass to go from 1m to 100m radius at 100m/s by switching tension from 10000N to 100N?(adsbygoogle = window.adsbygoogle || []).push({});

the object is spinning and i would like to know how many revolutions would it take to go from a radius of 1 m to a radius of 100 m starting to count in the moment the tension is switched from 10000N to 100N

i would apreciate any formula
