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?
h(t) = at2 + vt + h0

h = –16t2 + 60t + 4
h = –32t2 + 120t + 4
h = –32t2 + 60t + 2
h = –16t2 + 120t + 2

Option D -

Step-by-step explanation:

Given : Justin and Pedro each launched a toy rocket into the air. The height of Justin’s rocket is modeled by the equation .

Pedro launched his rocket from the same position, but with an initial velocity double that of Justin’s.

To find : Which equation best models the height of Pedro’s rocket?  

Solution :

Height of Justin rocket ,

Comparing with

a=-16 , v=60 ,

Pedro launched his rocket from the same position, but with an initial velocity double that of Justin’s.

Velocity is double i.e, v=2v

Substitute in equation we get,

Height of Pedro's rockets is

Therefore, Option D is correct.
