Question

a toy rocket is shot vertically into the air from a 9-foot-tall launching pad with an initial velocity of 144 feet per second. Suppose the height of the rocket in feet t seconds after being modeled by the function h(t)=-16² gthg. where v is the initial velocity of the rocket and he is the initial height of the rocket. How long will it take for the rocket to reach its maximum The rocker will reach its maximum height in second(s) launched can be height what s​

First, we need to find the maximum height that the rocket will reach. To do that, we need to find the vertex of the parabolic function h(t) = -16t^2 + 144t + 9. We can use the formula for the vertex of a parabola, which is given by the formula t = -b/2a, where a = -16 and b = 144.

t = -b/2a = -144/(2*(-16)) = 4.5

So the rocket will reach its maximum height after 4.5 seconds.

To find the maximum height, we need to substitute t = 4.5 into the function h(t):

h(4.5) = -16(4.5)^2 + 144(4.5) + 9 = 324

So the maximum height that the rocket will reach is 324 feet.

Therefore, the rocket will reach its maximum height of 324 feet after 4.5 seconds.
