Answer from Quizlet
Answer:
The average velocity is 2 m/s.
Explanation:
The velocity of the particle is the time derivative of its position 
![$v =\frac{dx(t)}{dt} = \frac{d}{dt}[t^2+2] $](https://tex.z-dn.net/?f=%24v%20%3D%5Cfrac%7Bdx%28t%29%7D%7Bdt%7D%20%3D%20%5Cfrac%7Bd%7D%7Bdt%7D%5Bt%5E2%2B2%5D%20%24)
Now the average from 
and 
is
Thus, the average velocity is 2 m/s.
When waves travel across strings, the larger the tension of the string the faster the velocity of the wave. This is because of the equation:
v = the square root of (T/(m/L)) where T is the tension, m the mass of the string, and L the length of the string
Hope this helps!
