Answer:
Time to land on 11ft is 4.25 seconds
Step-by-step explanation:
Given
![y = 300 - 16t^2](https://tex.z-dn.net/?f=y%20%3D%20300%20-%2016t%5E2)
Required
Solve for t when height is 11ft
This implies that ![y = 11](https://tex.z-dn.net/?f=y%20%3D%2011)
So: substitute 11 for y in ![y = 300 - 16t^2](https://tex.z-dn.net/?f=y%20%3D%20300%20-%2016t%5E2)
![11 = 300 - 16t^2](https://tex.z-dn.net/?f=11%20%3D%20300%20-%2016t%5E2)
Collect Like Terms
![16t^2 = 300 - 11](https://tex.z-dn.net/?f=16t%5E2%20%3D%20300%20-%2011)
![16t^2 = 289](https://tex.z-dn.net/?f=16t%5E2%20%3D%20289)
Express both sides as squares
![4^2 * t^2 = 17^2](https://tex.z-dn.net/?f=4%5E2%20%2A%20t%5E2%20%3D%2017%5E2)
![(4t)^2 = 17^2](https://tex.z-dn.net/?f=%284t%29%5E2%20%3D%2017%5E2)
Take square roots of both sides (ignore negative)
![4t = 17](https://tex.z-dn.net/?f=4t%20%3D%2017)
Solve for t
![t = \frac{17}{4}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B17%7D%7B4%7D)
![t = 4.25](https://tex.z-dn.net/?f=t%20%3D%204.25)
Hence, time to land on 11ft is 4.25 seconds
