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?
Well if he has doubled Justin's rocket the equation for this would be 2(16t2+60t+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
\(h= -16t^2+120t+2\)
