As light from a star races through our atmosphere, it bounces and bumps through the different layers, bending the light before you see it. Since the hot and cold layers of air keep moving, the bending of the light changes too, which causes the star's appearance to wobble or twinkle.
The perspective which best explain this is SOCIO-CULTURAL PERSPECTIVE.
Socio-cultural perspective is a theory which explains the awareness of situations surrounding people and how their behavior is determined by their environment, culture and social values.
Ok so we know:
The time (t) is 18seconds
The acceleration (a) is 2.2m/s2
The displacement (r) is 660
Using the equation
![r = ut + \frac{1}{2} a {t}^{2}](https://tex.z-dn.net/?f=r%20%3D%20ut%20%2B%20%20%5Cfrac%7B1%7D%7B2%7D%20a%20%7Bt%7D%5E%7B2%7D%20)
With 'u' being the initial velocity we want, we get:
![660 = 18u + 356.4](https://tex.z-dn.net/?f=660%20%3D%2018u%20%2B%20356.4)
So:
![18u = 303.6](https://tex.z-dn.net/?f=18u%20%3D%20303.6)
So:
![u = 16.8666](https://tex.z-dn.net/?f=u%20%3D%2016.8666)
So the original/initial velocity was 16.8666 or 16.87 m/s
Hope this helped
