Can anyone help me out?(adsbygoogle = window.adsbygoogle || []).push({});

The top has a moment of inertia

of 0:0002 kg.m2 and is initially at rest. It is

free to rotate about a stationary axis AA'. A

string, wrapped around a peg along the axis

of the top, is pulled in such a manner as to

maintain a constant tension of 5.22 N in the string.

If the string does not slip while wound

around the peg, what is the angular speed

of the top after 82.1 cm of string has been

pulled off the peg? Answer in units of rad/s

I have a problem with this question. I don't know how to calculate the linear distance given to an angular distance. I found the acceleration first using Torque=(I*acc). But then I don't know what to do next after this. My acceleration turned out to be 26100 rad/s^2
