The function \( h(t) = -16t^2 + 48t + 72 \) models the height above ground, in feet, of a toy rocket \( t \) seconds after it is launched from the roof of a building, assuming air resistance is ignored.

Based on the model, what is the height above ground, in feet, of the toy rocket 1 second after launch?

Answer :

The height of the rocket is found by plugging in the specified value of t in the height function

The height of the rocket 1 second after launch is 104 feet

The reason the height value above is correct is as follows:

A function is a relationship between inputs and outputs, such that an input is mappable to one output only

The given function for the height of the rocket is presented as follows;

  • h(t) = -16·t² + 48·t + 72

Where;

  • h = The height of the rocket above ground in feet
  • t = The time in seconds

The given function gives the height of the rocket above ground in feet t seconds after the rocket is launched

To find the height of the rocket 1 seconds after launch the value of t = 1 is plugged into the height function as follows;

h(1) = -16×1² + 48×1 + 72 = 104

Therefore, the height of the rocket 1 second after launch, h(1) = 104 feet
