As shown below, the end of the thread is pulled with a constant tension force F = 464 N, causing the thread to unwind from the peg without slippingu The top has a moment of inertia of 5.10 x 10'4 kg ~ m2. It is initially at rest and is free to rotate about the stationary axis AA'. what is the top's angular speed (in rad/s) after 70.0 cm of thread has unwound from the peg? lrad/s Need Help? nun 14.
