Answer:
f(t) = 15.06 m
Step-by-step explanation:
The relationship between the height of the rocket and the time after launch, t. In seconds is given by :
![f(t) = - 4.9t ^ 2 + 16t + 2](https://tex.z-dn.net/?f=f%28t%29%20%3D%20-%204.9t%20%5E%202%20%2B%2016t%20%2B%202)
We need to find the maximum height the rocket will reach the ground.
When it reaches the ground,
f(t) = 0
So,
Maximum height,
f'(t) = 0
![-9.8t+16=0\\\\t=\dfrac{16}{9.8}\\\\t=1.63\ s](https://tex.z-dn.net/?f=-9.8t%2B16%3D0%5C%5C%5C%5Ct%3D%5Cdfrac%7B16%7D%7B9.8%7D%5C%5C%5C%5Ct%3D1.63%5C%20s)
Put t = 1.63 in equation (1).
![f(1.63) = - 4.9\times (1.63 ^ 2) + 16(1.63) + 2\\\\=15.06\ m](https://tex.z-dn.net/?f=f%281.63%29%20%3D%20-%204.9%5Ctimes%20%281.63%20%5E%202%29%20%2B%2016%281.63%29%20%2B%202%5C%5C%5C%5C%3D15.06%5C%20m)
So, the maximum height of the rocket is 15.06 m.
