Answer:
Explanation:
For this case we can use the following formula for the angular velocity:
where represent the final angular velocity , the initial angular velocity , t the time and the angular acceleration.
And for the linear acceleration we have this formula:
Where a represent the linear acceleration and the angular acceleration.
For this case the linear acceeleration is given
And the radius of the yo-yo is also given
So then we can use the following formula:
If we replace the values we got:
And solving for we got:
