When a mass of 3.0-kg is hung on a vertical spring, it stretches by 0.085 m. Determine the period of oscillation of a 4.0-kg object suspended from this spring.

the period of oscillation of the given object is 0.14 s

Explanation:

Given;

mass of the object, m = 3 kg

extension of the spring, x = 0.085 m

The spring constant is calculated as follows;

The angular speed of a 4 kg object is calculated as follows;

Therefore, the period of oscillation of the given object is 0.14 s

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

option number c is the right answer.
