Answer:
Angular speed,
Explanation:
It is given that,
The top of the leaning bell tower at Pisa, Italy, moved toward the south at an average rate of, v = 1.2 mm/yr
Velocity,
Height of the tower, h = 55 m
The height of the tower is equivalent to the radius. Let is the angular speed of the tower’s top about its base. The relation between the angular speed and the angular speed is given by :
So, the average angular speed of the tower’s top about its base is . Hence, this is the required solution.
