Answer:
b) se duplica
Explanation:
The disk is moving with constant angular velocity, let's call it 
.
The linear velocity of a point on the disk is given by
where r is the distance of the point from the axis of rotation.
In this problem, the object is moved at a distance twice as far as the initial point, so
Therefore, the new linear velocity is
So, the velocity has doubled, and the correct answer is
b) se duplica
Ummm I’m not sure let me do the work
