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?

h(t) = at2 + vt + h0
h = –16t2 + 60t + 4
h = –32t2 + 120t + 4
h = –32t2 + 60t + 2
h = –16t2 + 120t + 2

Answer 1

I thunk the equation is h = –32t2 + 60t + 2 because double initial velocity mean double time in the air which will reach a higher height but since the constant"2" of the equation doesn't have a t with it ,it remains tge same for Pedro rocket where the other term doubled.Hope this help.

Answer 2

Answer: h = -16t^2 + 120t + 2
