A model rocket launched directly upward at a speed of 16 meters per second from a helght of 2 meters . The f(t) = - 4.9t ^ 2 + 1
Anton [14]

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

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

Put t = 1.63 in equation (1).

f(1.63) = - 4.9\times (1.63 ^ 2) + 16(1.63) + 2\\\\=15.06\ m

So, the maximum height of the rocket is 15.06 m.
