Answer:
The final velocity is ![V = 30.25 \frac{m}{s}](https://tex.z-dn.net/?f=V%20%3D%2030.25%20%5Cfrac%7Bm%7D%7Bs%7D)
Step-by-step explanation:
<em>The car starts from rest, this means the initial velocity U = 0.</em>
The time interval is <em>8 seconds.</em>
The total Distance traveled is <em>121 meters.</em>
The formula for calculating final velocity(V) is,
![(distance) = U(time) + (\frac{1}{2})(acceleration)((time)^{2})](https://tex.z-dn.net/?f=%28distance%29%20%3D%20U%28time%29%20%2B%20%28%5Cfrac%7B1%7D%7B2%7D%29%28acceleration%29%28%28time%29%5E%7B2%7D%29)
![121 = (0)(8) + (\frac{1}{2})(a)(64)](https://tex.z-dn.net/?f=121%20%3D%20%280%29%288%29%20%2B%20%28%5Cfrac%7B1%7D%7B2%7D%29%28a%29%2864%29)
a= ![\frac{121}{32}](https://tex.z-dn.net/?f=%5Cfrac%7B121%7D%7B32%7D)
The final velocity is given by,
![V = (0) + (a)(time)](https://tex.z-dn.net/?f=V%20%3D%20%280%29%20%2B%20%28a%29%28time%29)
![V = (\frac{121}{32})(8) = 30.25 \frac{m}{s}](https://tex.z-dn.net/?f=V%20%3D%20%28%5Cfrac%7B121%7D%7B32%7D%29%288%29%20%3D%2030.25%20%5Cfrac%7Bm%7D%7Bs%7D)

She rode her bike for 6 hours
Step-by-step explanation:
you take away the initial fee 20$ and get 27 then divide 27 b7 4.5 or 4.50$ and get 6
Answer:
y+2=2x-4
Step-by-step explanation:
Answer:
110 and 100
Step-by-step explanation:
Angle 2 will have the same messurement as the one across, so 110
Angle 1 will be the difference between 180 and 80, so 100
Answer:
The slope of the line is 2
Step-by-step explanation:
In this problem you need to know rise over run. This means the slope goes up two and the over one. This makes the slope 2.
