Answer:
Explanation:
Given that,
Mass of an object, m = 3.68 kg
It is whirled in a horizontal circle of radius 881 cm or 8.81 m
The object completes 10.8 revolutions every 18.8 s.
We need to find the centripetal acceleration of the object. It is given by the formula as follows :
...(1)
Where is angular velocity
10.8 revolutions = 67.85 rad
Put values in equation (1)
So, the centripetal acceleration of the object is .
