Question

Justin and Pedro each launched a toy rocket into the air. The height of Justin’s rocket is modeled by the equation h = –16t2 + 60t + 2. Pedro launched his rocket from the same position, but with an initial velocity double that of Justin’s. Which equation best models the height of Pedro’s rocket?

Answer 1

Well if he has doubled Justin's rocket the equation for this would be 2(16t2+60t+2).

Answer 2

Answer:

Equation of Pedro's   rocket  

$h= -16t^2+120t+2$

Equation of Pedro's   rocket  $h= -16t^2+120t+2$

Step-by-step explanation:

$h= -16t^2+60t+2$

on comparing the given equation with general equation

$h= -gt^2+vt+h_{0}$

           we get v = 60 feet /second which is the speed of Justin's rocket.

          Speed of  Pedro's rocket = double of Justin's rocket

                                                     = 2(60 ) = 120 feet second

therefore equation for Pedro will be given by

$h= -16t^2+120t+2$
