An object moves around a circular path at a constant speed and makes five complete revolutions in 20 seconds. What is the period of rotation? A)4 s
B)5 s
C)20 s

The period of rotation of the object around a circular path is: A) 4 seconds.

Given the following data;

To find the period of rotation;

Mathematically, the number of oscillation of an object around a circular path is given by the formula;

Making period the subject of formula, we have;

Substituting the values into the formula, we have:

Period = 4 seconds

Therefore, the period of rotation of the object around a circular path is 4 seconds.
