Answer:
![v(1) = 2\ ft/s](https://tex.z-dn.net/?f=v%281%29%20%3D%202%5C%20ft%2Fs)
Step-by-step explanation:
Given
![s(t) = 4t^2-5t+3](https://tex.z-dn.net/?f=s%28t%29%20%3D%204t%5E2-5t%2B3)
Required
Determine the instantaneous velocity at ![t = 1](https://tex.z-dn.net/?f=t%20%3D%201)
First, we need to determine s(1)
![s(t) = 4t^2-5t+3](https://tex.z-dn.net/?f=s%28t%29%20%3D%204t%5E2-5t%2B3)
![s(1) = 4(1)^2 - 5(1) + 3](https://tex.z-dn.net/?f=s%281%29%20%3D%204%281%29%5E2%20-%205%281%29%20%2B%203)
Evaluate all brackets
![s(1) = 4*1 - 5*1 + 3](https://tex.z-dn.net/?f=s%281%29%20%3D%204%2A1%20-%205%2A1%20%2B%203)
![s(1) = 4 - 5 + 3](https://tex.z-dn.net/?f=s%281%29%20%3D%204%20-%205%20%2B%203)
![s(1) = 2](https://tex.z-dn.net/?f=s%281%29%20%3D%202)
Next; v(t) is calculated as thus;
![v(t) = \frac{s(t)}{t}](https://tex.z-dn.net/?f=v%28t%29%20%3D%20%5Cfrac%7Bs%28t%29%7D%7Bt%7D)
Substitute 1 for t
![v(1) = \frac{s(1)}{1}](https://tex.z-dn.net/?f=v%281%29%20%3D%20%5Cfrac%7Bs%281%29%7D%7B1%7D)
Substitute 2 for s(t)
![v(1) = \frac{2}{1}](https://tex.z-dn.net/?f=v%281%29%20%3D%20%5Cfrac%7B2%7D%7B1%7D)
![v(1) = 2\ ft/s](https://tex.z-dn.net/?f=v%281%29%20%3D%202%5C%20ft%2Fs)
