Social Network Research While Facebook and LinkedIn are well established networking sites, researchers are just beginning to figure out and experiment with how to conduct scholarly research using these technologies. A journal titled, "Cyberpsychology, Behavior, and Social Networking" focuses on this topic, as well as other technology related issues. Perhaps this is a journal to which you could submit your final assignment for publication. For this discussion, please watch, "TED Talks: Nicholas Christakis --The Hidden Influence of Social Networks." The speaker provides examples and stories regarding how social networks are being studied. Please answer the following questions for your initial post: How can you apply networking research to the workplace? How does social networking impact global organizations and our work as IO psychologists? What are some research questions involving networking and/or social networking that you might want to look into at some point? Now, check out The LINKS Center for Social Network Analysis (https://sites.google.com/site/uklinkscenter/home(Links to an external site.)). Click on "Research" and identify at least one article that is of interest to you (note that there are PDF versions for almost every article). Share the article title and major ideas in your post. Propose additional areas of research or potential research questions in the area of social network analysis that are relevant to a peer's post and/or interests. Utilize at least one scholarly, peer-reviewed journal article as a resource. Your post should be at least 300 words. HW15 Handout Name: ___________________ 1.

1. A spring-mass system has a period of 2.1 s. At t = 0 it is at rest at x = -15 cm. Its equilibrium position is x = 0. a. Give symbolic equations for the position, velocity, and acceleration as functions of time.
Solution:
Assume the system to be horizontal in nature (no gravity). The spring-mass system is a simple harmonic oscillator. This follows the main second order differential equation of motion, which is given by
(1)
Therefore it follows the equation for position is given by
(2)
Where, is the amplitude and its value is given as 0.15m.
And thus the equation for velocity is given by
(3)
b. Find the maximum speed of the mass? At what t does this occur?
Solution:
Now, at the middle (x=0), the acceleration is zero.
Therefore, to get the maximum velocity its first derivative is zero.
i.e.
From this,
(4)
Now, all (5)
Therefore, (6)
For

And hence the value of t can be calculated, using the value of
Thus, (7)
Similarly, the value of maximum velocity can be calculated using equation (3) and (6)

2.A spring with a force constant of 70 N/mis hung from the ceiling. A block of mass 0.27 kg is hung from it and set in simple harmonic motion with an amplitude of 8 cm. What is the maximum speed of the mass? Watch your units!
Solution:
Given
